Getmail is a nice little program that works in a similar way to fetchmail. getmailx so the Debian using reader might wish to use 4.x rather than 3.x). getmail is a mail retriever designed to allow you to get your mail from one or more mail accounts on various mail servers to your local. Manually, it would take you around 5 minutes to find an email when it only takes you a few seconds with GetEmail. If you search 20 email addresses per day. CITRIX SYNERGY 2020

Unfortunately, some MTAs do not always do this properly, and envelope information can then be lost. When this happens, it makes dealing with certain types of mail messages problematic:. MTAs are supposed to record the envelope sender address by placing it into a new Return-Path: header field at the top of the message. They should then record the envelope recipient address es in another new header field; sometimes this header field is named Delivered-To: , but it can also be Envelope-To: or one of a few other names.

A domain or multidrop mailbox is one which receives mail for multiple email addresses commonly all addresses in a given domain. You cannot do this by looking at the To: , cc: , or other informational message header fields, because they do not actually reflect the message envelope at the time of delivery. Instead, you have to reconstruct the envelope information from the message header fields which the MTA on the server used to record it at the time of delivery.

If the final MTA does not record the message envelope the envelope sender, and all envelope recipient addresses in the domain mailbox the message was sent to , then mail will be lost or misdirected regardless of which software you use to access the mailbox.

The mailbox cannot actually be said to be a domain mailbox in this case; the defining characteristic of a domain mailbox is that it records the envelope correctly. The configuration of the MTA running on the server needs to be fixed so that the envelope is properly recorded for every message it receives. The configuration file format is actually very simple; you don't need to worry about most of it if you're not interested in using those features.

The simplest and most common getmail rc file configuration will be for users who want to retrieve all mail from a single-user POP3 mailbox, deliver those messages to a maildir or mbox file, and delete the mail from the server. For maildir, that configuration is:. Create a separate getmail rc file for each account, and run getmail with multiple --rcfile options. Use the received [options] parameter.

You don't need to. If you still think you need to, you can use getmail's external MDA support to do so. Use the maildirmake command, if you have it installed. Otherwise, run the following command from your shell:. Some other maildir-aware programs ship with their own maildir-creation programs; you can use those, or make the above shell command a shellscript or alias if you like.

Create a completely empty i. The standard utility touch is commonly used:. In nmh, this command is called rcvstore. You just run getmail under whatever process-supervision or periodic-job system you already have on your system. That example would run getmail continuously, sleeping for 30 minutes between runs. You can probably work out similar scripts for other process-supervision systems.

If you don't have such a system, you can use your system's cron utility to run getmail periodically, but you absolutely have to prevent multiple copies of getmail from being run by cron simultaneously. Most versions of cron have no protection for this built-in, so you have to use setlock or flock or a similar utility to prevent it. For more details, see How do I stop multiple instances of getmail from running at the same time? If you do not prevent multiple copies of getmail running against the same server and IMAP folder simultaneously, you will get odd behaviour, including retrieving the same messages multiple times.

Some users with flaky servers use this option to reduce the chances of seeing messages more than once if the server dies in mid-session. Well, you could write a retriever that speaks Hotmail's proprietary, undocumented, and unsupported access protocol, or simply set up the POP3 proxy from the httpmail package, and have getmail retrieve mail from that POP3 proxy.

These are supplementary questions I occasionally see about doing various things to enhance a getmail setup. The solution to many of them is to use a standard Unix technique of some sort to make the system behave in a certain manner, or otherwise change the behaviour of something that's actually outside of getmail proper.

Some people ask about temporarily stopping getmail from running from a cron job, possibly because the mail server is down and they don't want to see the warnings cron mails them. The easiest method is to comment out getmail from your crontab file:.

If you need to do this on a regular basis, you can instead use a "flag file" to tell the system whether or not to run getmail :. Change your cron job or shellscript that normally launches getmail to check for the presence of a certain file first, and have it not run getmail if that file is present.

For example, your crontab entry could be changed to do this:. This is even safe for scripting, as creating and removing the file are atomic operations under Unix. In particular, if you're running getmail from a crontab, you must do something to prevent cron from starting getmail if the previous invocation is still running. If you need to prevent two instances of getmail from running simultaneously, use any standard Unix method of providing a mutex for this purpose. One example would be to run getmail under a program like setlock part of the daemontools package.

Change your script or crontab file to invoke getmail like this:. There are other programs that provide functionality similar to setlock. In both configurations, SpamAssassin accepts a wide variety of arguments; please refer to SpamAssassin's manual pages or online documentation for details. The value supplied to the -s option is the maximum message size accepted in bytes.

The default is k. A similar configuration without the spamd daemon would be:. The --report option sends the message to the various spam-blocker databases and tags it as spam in your bayesian database. That is, the headers added by the other filters may get learned, and affect your database. To prevent this, ensure that SpamAssassin ignores these fields by adding the following to your SpamAssassin configuration:.

You should also read this message in the getmail users' mailing list archives and the ClamAV documentation if you want to use ClamAV with getmail. In either case, you need to add the StreamSaveToDisk option to your clamav. To use ClamAV without the clamd daemon, use a filter configuration like this:. The above assumes you do not want the infected emails to be delivered. If you do want them delivered, you would use a slightly different configuration:.

To use ClamAV with the clamd daemon, use a filter configuration like this:. As with Clamscan above , if you do want the infected messages delivered instead of dropped, you should modify your configuration as follows:. You may find it necessary to specify the paths of some decompression utilities used by ClamAV with additional arguments like:.

The paths to the various decompression utilities must be specified in this file as well. This can make auditing the actions of filters difficult if you use multiple filters and cannot tell which filter added which line. To correct this, you can use an additional filter to change the name of the added filter header lines immediately after each filter is run.

For example, reformail , from the maildrop package which is in turn part of the Courier MTA can be used in this fashion to rename the added header fields say, to "X-mypersonalmailscan" with a filter configuration like this:. Simply ensure ClamAV is invoked as the first filter, and this is invoked as the second filter or immediately after the ClamAV filter, if it is the second, third, etc.

The wrapper script f-prot-wrapper. Simply invoke procmail as an external MDA. To supply the -f option to procmail, do something like this:. Simply invoke maildrop as an external MDA. One of the following would be fine:. If you want to specify a maildrop rc file as one of its arguments, that would be something like:.

As of getmail version 4. There are frequent reports like the following, which aren't bugs in getmail. Please read them before reporting them as bugs. There's a couple of different problems here. They do this as soon as an RETR command is given, so if getmail tries to download a message and it fails for any reason delivery fails due to a full disk, or the Gmail server fails to respond, or the network connection dies before the transfer is complete, or the Gmail server fails to respond to the QUIT command, or … , the next time getmail connects to that Gmail account, Gmail will have "helpfully" deleted the message from the POP3 mailbox, even though getmail never issued a DELE command.

So Gmail silently destroys mail, from a POP3 perspective. There's nothing getmail can do about this. Note this feature of Gmail is not well-publicized. The other issue here is that Google doesn't include mail from your trash or spam folders in the POP3 view, so getmail can't see those messages either. That's generally less of an issue, provided their spam filters never give false positive results ha! The server you're trying to use does not properly uniquely identify messages getmail noticed when it saw the same "unique" identifier twice in the same mailbox at the same time.

The OS X implementation of realloc is broken , and there's nothing getmail can do about it. To work around the problem, upgrade to getmail v. What is getmail6 and how does it relate to getmail?

You should include at least the following information: getmail version Python version any error message which getmail displayed the output from running getmail with your normal options plus --dump if your problem is getmail not determining the proper local recipient, please include the output of running getmail with your normal options plus --trace , showing the retrieval of one problematic message.

The below text is by Charles Cazabon, getmail's original author: Short answer: … well, the short answer is mostly unprintable. The long answer is … well, long: I do not like some of the design choices which were made with fetchmail. For instance, fetchmail's configuration file syntax has been criticized as being needlessly difficult to write; instead of cleaning up the syntax, the maintainer instead included a GUI configuration-file-writing program, leading to comments like: The punchline is that fetchmail sucks, even if it does have giddily-engineered whizbang configurator apps.

As an example, Dan Bernstein , author of qmail and other software packages , once noted to the qmail list: Last night, root xxxxxxxxxxxxxxxxx reinjected thirty old messages from various authors to qmail xxxxxxxxxxxxxx This sort of idiocy happens much more often than most subscribers know, thanks to a broken piece of software by Eric Raymond called fetchmail.

Filters can tell getmail to drop a message i. You can specify any number of filters; provide a separate rc file section for each, naming each of them filter- something. They will be run in collated order, so it's likely simplest to name them like this:. Then, include a type string parameter to tell getmail what type of filter. By default, if a filter writes anything to stderr , getmail will consider the delivery to have encountered an error.

You must configure any filter you use not to emit messages to stderr except on errors — please see the documentation for your filter program for details. As TMDA relies on the message envelope, this filter requires the use of a multidrop retriever class to function. I would appreciate any feedback about its use from TMDA users. You might filter spam messages in your MUA based on information added to the message header by a spam-classification program.

You could have that information added to the message header with a filter configuration like this:. You might use a program to prevent users from accidentally destroying their data by stripping suspected attachments from messages. You might use TMDA to challenge messages from unknown senders. If the default parameters are fine for your configuration, this is as simple as:. Several examples of different getmail rc configuration are available in the included file getmailrc-examples.

In addition, the following commandline options can be used to override any values specified in the [options] section of the getmail rc files:. Then run getmail as follows:. If those files were located in a directory other than the default, and you wanted to use that directory for storing the data files as well, you could run getmail as follows:.

It reads the mail message from stdin, and delivers it to a maildir path provided as an argument on the commandline. This path must after expansion by the shell, if applicable start with a dot or slash and end with a slash.

The default is to operate silently unless an error occurs. You could deliver a message to a maildir named Maildir located in your home directory by running the following command with the message on stdin:. It reads the mail message from stdin, and delivers it to an mbox path provided as an argument on the commandline. This path must after expansion by the shell, if applicable start with a dot or slash and not end with a slash.

You could deliver a message to an mboxrd-format mbox file named inbox located in a directory named mail in your home directory by running the following command with the message on stdin:. It is primarily intended for use in automated or scripted environments, but can be used to retrieve mail normally.

How do I know if I have one? Configuring getmail How do I … Using getmail with other software I think I found this bug in getmail … Configuring getmail Once getmail is installed , you need to configure it before you can retrieve mail with it.

If you choose a different location, you will need to specify it on the getmail command line. In general, other users should not be able to read the contents of this directory, so you should set the permissions on it appropriately. The default name is getmailrc. If you choose a different filename, you will need to specify it on the getmail command line.

If you want to retrieve mail from more than one mail account, you will need to create a separate rc file for each account getmail should retrieve mail from. Creating a getmail rc file The configuration file format is designed to be easy to understand both for getmail, and for the user. Parameter types and formats Several different types of parameters are used in getmail rc files: string integer boolean tuple of quoted strings tuple of integers tuple of 2-tuples Each parameter type has a specific format that must be used to represent it in the getmail rc file.

Begin with the section header line as follows: [retriever] Then, include a type string parameter to tell getmail what type of mail retriever to use to retrieve mail from this account. What is a "multidrop" mailbox? If the message incorrectly already contained such a header field, it must be deleted before the envelope sender address is recorded.

These may be named various things, but are commonly Delivered-To , X-Envelope-To , and similar values. In the case of messages which had multiple recipients in the domain, this must be a single address, reflecting the particular recipient of this copy of the message.

Note that this field and the envelope recipient address are not related to informational header fields created by the originating MUA, like To or cc. Common retriever parameters All retriever types take several common required parameters: server string — the name or IP address of the server to retrieve mail from username string — username to provide when logging in to the mail server All retriever types also take several optional parameters: port integer — the TCP port number to connect to.

If not provided, the default is a port appropriate for the protocol for POP3, etc. If this option is not recognized, your Python installation does not have Python keyring. The program must write the password and nothing else to stdout, and must exit with a status of 0 on success. Note that the password parameter above overrides this parameter; specify one or the other, not both.

This parameter is specified as the program to run as the first string in the tuple, and all remaining strings are arguments passed to that program. Consult your server's documentation or postmaster if you're unsure what form your server uses. If your mailbox names contain non-ASCII characters, ensure that your getmailrc file is stored with UTF-8 encoding so that getmail can correctly determine the unicode character names that need to be quoted in IMAP's modified UTF-7 encoding; if you do not do this, the mailbox names will not match what the server expects them to be, or will cause UnicodeErrors when attempting to load your getmailrc file.

As a special case, in getmail version 4. Versions of getmail prior to 4. The specified mail folder must exist; getmail will not create it. Note that if you configure getmail not to delete retrieved messages the default behaviour , they will not be moved at all. This is on by default, but can be disabled. If not set, normal password-based authenticaion is used.

Note that when you use Kerberos authentication, it is up to you to ensure you have a valid Kerberos ticket perhaps by running a ticket-renewing agent such as kstart or similar. This is currently only supported with Gmail; if anyone extends this to support other IMAP providers, please let me know so I can include such support in getmail.

This functionality was contributed by Stefan Krah, who has additional information about using it here. SSL Client Parameters All SSL-enabled retriever types also take the following options, to allow specifying the use of a particular client key and client certificate in establishing a connection to the server. Specify the path to a PEM-formatted list of 1 or more valid and trusted root certification authority CA certificates.

Note: this option is only available with Python 2. Root certificates are not supplied with getmail; your OS probably installs a set by default for use by the system, or you may wish to use a specific set of trusted root certificates provided by your employer or a trusted third party. See the Open SSL documentation for details. If the specified setting results in no possible ciphers available, getmail will abort the connection.

Another useful value is probably "sslv3". The available option values are taken from the Python ssl module. Note that this option exists only to help in connecting certain legacy, out-of-date, broken servers; most users should not specify this option at all. Using this option without knowing what you are doing can reduce the effectiveness of your encrypted connection. Supply a list of one or more SHA certificate fingerprints, and getmail will confirm whether the server's certificate fingerprint is in the list of allowed fingerprints; if it is not, getmail will abort the connection.

Getmail will log the fingerprint of the server's certificate if you supply the --fingerprint commandline option. Specify this if the name used to connect to the server is known not to match the hostname in the server's certificate; otherwise, getmail will error out with a hostname mismatch. This is not supported by many POP3 servers. The default is False. If not specified, the default is seconds. You may need to increase this value in particularly poor networking conditions.

Begin with the section header line as follows: [destination] Then, include a type string parameter to tell getmail what type of mail destination this is. The possible values are: Maildir — deliver all messages to a local qmail-style maildir Mboxrd — deliver all messages to a local mboxrd-format mbox file with fcntl-type locking.

Typical MDAs include maildrop , procmail , and others. MultiDestination — unconditionally deliver messages to multiple destinations maildirs, mbox files, external MDAs, or other destinations. MultiSorter — sort messages according to the envelope recipient requires a domain mailbox retriever and deliver to a variety of maildirs, mbox files, external MDAs, or other destinations based on regular expressions matching the recipient address of each message.

Messages not matching any of the regular expressions are delivered to a default "postmaster" destination. MultiGuesser — sort messages according to getmail's best guess at what the envelope recipient of the message might have been, and deliver to a variety of maildirs, mbox files, external MDAs, or other destinations based on regular expressions matching those addresses. Maildir The Maildir destination delivers to a qmail-style maildir. Note that this typically requires root privileges.

Note that the current umask is masked out of the given value at file creation time. The default value, which should be appropriate for most users, is "". Mboxrd The Mboxrd destination delivers to an mboxrd-format mbox file with either fcntl-type lockf or flock-type file locking. The Mboxrd destination takes one required parameter: path string — the path to the mbox file. The default in getmail 4. Defaults to false. Some MDAs expect such a line to be present and will fail to operate if it is missing.

The default is false, which causes getmail to raise an exception if it is asked to run an external command as root. Note that setting this option has serious security implications. Don't use it if you don't know what you're doing. I strongly recommend against running external processes as root. The default is false, which causes getmail to consider the delivery failed and leave the message on the server, proceeding to the next message.

This prevents loss of mail if the MDA writes to stderr but fails to exit nonzero when it encounters an error. Note that setting this option has serious implications; some MDAs can fail to deliver a message but still exit 0, which can cause loss of mail if this option is set.

Only change this setting if you are confident your MDA always exits nonzero on error. The MultiDestination destination takes one required parameter: destinations tuple of quoted strings — the destinations which the messages will be passed to. The MultiSorter destination takes one required parameter: default string — the destination for messages which aren't matched by any of the "locals" regular expressions. The destination can be a maildir, mboxrd file, or other destination. See MultiDestination for an explanation of how the type of destination is interpreted from this value.

The MultiSorter destination also takes one optional parameter: locals tuple of 2-tuples — zero or more regular expression — destination pairs. Messages will be delivered to each destination for which the envelope recipient matches the given regular expression. The regular expression and destination are supplied as two quoted strings in a tuple; locals is then a tuple of such pairs of strings. Destinations are specified in the same manner as with the "default" parameter, above. Handy hints: the regular expression.

Using regular expressions: The regular expression joe example. The regular expression sam matches the addresses sam example. Some examples: Deliver mail matching jeff example. MultiGuesser extracts a list of addresses from the message header like this: it looks for addresses in any Delivered-To: header fields.

The MultiGuesser destination takes one required parameter: default string — see MultiSorter for definition. The MultiGuesser destination also takes one optional parameter: locals tuple of 2-tuples — see MultiSorter for definition. Examples: If you have a simple POP3 account i. The default value is the account name of the current effective UID. The default value is the home directory of the account with the current effective UID.

The default value is the fully-qualified domain name of the local host. The default value is. The default value is -. This can be used to remap recipient addresses, trim extraneous prefixes such as the qmail virtualdomain prepend value , or perform other tasks. The default value is '', '' i. This may be necessary to prevent qmail-local falsely detecting a looping message if for instance the system retrieving messages otherwise believes it has the same domain name as the retrieval server.

Inappropriate use of this option may cause message loops. The default value is False. The parameters supported in this section are as follows: verbose integer — controls getmail's verbosity. If set to 2, getmail prints messages about each of its actions. If set to 1, it prints messages about retrieving and deleting messages only.

If set to 0, getmail will only print warnings and errors. Default: 1.

For this guide we will be storing our mail in the maildir format. The two main mailbox formats are mbox and maildir. The main difference between the two is that mbox is one file, with all of your mails and their headers stored in it, whereas a maildir is a directory tree. Each mail is its own file, which will often speed things up.

A maildir is just a folder with the folders cur , new and tmp in it. Now, run getmail. Type crontab -e to edit cronjobs, and enter the following:. Also, to quiet getmail down, we can reduce its verbosity to zero by adding the following to getmailrc. By default, when you run getmail the program searches for the file getmailrc created as seen above.

If you have more than one mail account you would like to get mail from, then you can create such a file for each email address, and then tell getmail to run using both of them. Obviously if you have two accounts and two files you cannot have both of them called getmailrc. What you do is give them two different names, using myself as an example: I call one personal, and one university.

These two files contain content relevant to my personal mail, and my university work mail respectively. On GNU-ish Unix-like systems, this means:. Then, change into the extracted getmail directory and start the build process. The easiest installation method is to use the included setup. Alternatively, you can build a binary package i. When that completes in a few seconds, become root and then install the software. You can install in the default location, or specify an alternate location to install the software, or specify alternate directories for only part of the package.

To install in the default location, become user root and install with the following commands:. You can specify an alternate prefix directory by supplying the --prefix option to the install command, like this:. This will install the various parts of the package in subdirectories like in the default installation see the section Installing in the default location above , but under your specified prefix directory.

Note, however, that the getmailcore package will not be in the default Python module search path if you do this; see the section Installing the getmailcore package in a non-standard location if you use this option. If you only want to change the directory for some of the components, use the following options:. You will need to do one of the following to make those files available to the scripts:. See the documentation at the Python.

It is strongly recommended that you install the Python library files in the site-packages directory which Python provides for exactly this reason. To build a binary package from the included source, run the following command from inside the unpacked getmail source.
