	Procmail - Wikipedia, the free encyclopedia
		Procmail is a mail delivery agent (MDA) or mail filter, a program to process incoming emails on a computer, widely used on Unix systems.
		Common operations carried out with procmail include filtering and sorting of emails into different folders according to keywords in from, to, subject or text of the mail, or sending autoreplies, but more sophisticated operations are also possible.
		Procmail is also known for it's highly unreadable source code.

		Procmail can also be used as a general purpose mail filter, i.e., pro- visions have been made to enable procmail to be invoked in a special sendmail rule.
		Procmail will setuid to the intended recipients and delivers the mail as if it were invoked by the recipient with no arguments (i.e., if no rcfile is found, delivery is like ordinary mail).
		Procmail is not the proper tool for sharing one mailbox among many users, such as when you have one POP account for all mail to your do- main.

		Procmail version 3.22 is a bugfix release that resolves all known regression issues seen in versions 3.20 and 3.21.
		Procmail version 3.15.1 fixed a race condition when creating mailboxes that could result in a bounced message and increased the paranoia with which the initial environment is handled when using the -p flag.

	Unix Procmail Configuration
		Procmail is a free open-source package of tools that you can use to automatically process messages either as they arrive or after they are already in a mailbox.
		In Procmail, regular expressions are used in the conditions of a recipe to, for example, look for a pattern in the Subject header of a message.
		The one with procmail testing in the Subject should be in the mailbox $MAILDIR/in-testing and the one without test in the Subject should be in your default inbox.

		Lost "x" Procmail tried to clone itself but could not find back rcfile "x" (it either got removed or it was a rel- ative path and you changed directo- ry since procmail opened it last time).
		Procmail uses the regular TERMINATE signal to terminate any runaway filter, but it does not check if the filter responds to that signal and it only sends it to the filter itself, not to any of the filter's children.

	Enhancing E-Mail Security With Procmail - Home
		Procmail is a program that processes email messages looking for particular information in the headers or body of each message, and takes actions based on what it finds.
		If you're familiar with the concept of "rules" as provided in many major user mail clients (such as the cc:Mail client), then you are already familiar with the concept of automatically processing email messages based on their content.
		This procmail ruleset is specifically designed to "sanitize" your email on the mail server, before your users even attempt to retrieve their messages.

	Procmail Module Library homepage
		Procmail is a mail processing utility, which can help you filter your mail, sort incoming mail according to sender, Subject line, length of message, keywords in the message, etc, implement an ftp-by-mail server, and much more.

	Timo's procmail tips and recipes
		procmail material on the net, here are some of my own tips and observations.
		The "^TO_" in the first recipe is a procmail reserved predefined special expression "which should catch all destination specifications containing a specific address." It must be written in upper case.
		Procmail's companion program formail is used to extract all the "Received:" routing information from the posting's header.

		This sould be defined if you want procmail to use the console (or any other terminal or file -- replace `/dev/console' with the file you want to use) to print any error messages that could not be written to the logfile.
		Within the procmail script, $1 is the name of the sender and $2 is the name of the recipient.
		Procmail expects exactly one mail message to be presented to it on its stdin.

	Procmail Links
		For completeness' sake, a link back to my attempt at a Procmail FAQ and to a Procmail Quick Reference (which is still a beta version, but hopefully useful to somebody).
		Procmail makes for a very nice framework for filtering spam, although your provider should also offer other front-line defenses such as total blocking of all connections from known spam factories.
		Jari's Procmail tips page is also available in a text-only version; this is a vast and sometimes slightly verbose collection of bits and pieces of Procmail information.

	procmail
		Procmail is an automatic mail processing program, developed by Stephen van den Berg in Aachen, Germany and currently running on tigger and icarus.
		After you turn procmail on -- by creating a.procmailrc file and putting it in your home directory -- procmail will process each note you receive, when you receive it, according to the group of "recipes" you devise for it.
		Each procmail recipe consists of one or more conditions, like "Is this note from John?" or "Is this note about electronic mail?", followed by an action like "file it in my john.inbox" or "forward it to Bob".

	Procmail Tips
		Procmail is powerful mail handling tool and a lot of space here has been devoted to discuss about UBE (aka Spam) and its essence.
		Procmail will only detect a write error in such a case if the mail is long enough and does not fit in the pipe buffer that's in the kernel (typically 10KB).
		Procmail only forks a full-blown clone on a recipe with the 'c' flag whose action is a nested block.

	Procmail Quick Reference Guide
		This Quick Reference is a companion document to the Procmail FAQ which is available from http://www.iki.fi/era/procmail/mini-faq.html and a number of mirrors.
		Recall that Procmail is normally not paying attention to character case, so this matches A through Z, too (unless you use the D flag to prevent that).
		How long Procmail must wait in vain before it is allowed to decide the existing lock on a file must have been stale, and proceed to break the lock.

	Third-Party Software
		rblcheck was really designed to be used with procmail, as long as you have access to the IP address of the system sending you email.
		One more thing: procmail has a nasty habit of munging the environment, but most MTAs already do this for you.
		Hence, you should add the '-p' flag to the invokation of procmail (either from a local delivery rule in Sendmail, or from a.forward or.qmail file).

		And if you want to receive mail from me even if I sent it to twelve other people, you would put this test BEFORE the one for "too many recipients." The first recipe that 'delivers' the message, whether to a mailbox or to the wastebasket, is the LAST test that will be done.

	ii.com · Procmail Quick Start: An introduction to email filtering with a focus on procmail by Nancy McGough
		A mailbox might be a single flat file (this is the structure used by spool (mbox) and c-client MBX mailboxes); it might be a directory with each message a file in the directory (this is the structure of MH, maildir, and Netnews mailboxes); or it might use some other data structure to group messages.
		Procmail “normal egrep” regular expressions do not support all the metacharacters that are used in GNU egrep.
		It is not needed at the beginning or end of a Procmail regular expression (except when you are using the extraction operator and you want to extract all characters either from the beginning of the line or through to the end of the line).

		Rather than try to exhaust the possibilities, here are some samples of procmail recipes that I have found useful, with comments about how they were constructed.
		That night I did a quick web search that confirmed this was a known, named problem, SirCam32, that was just starting to take off, and the reputable anti-virus sites already had enough information to allow me to make a comprehensive set of filters.
		This is a lot more # work for procmail and your computer, so use these tests sparingly.

	[LinuxBrit] - Procmail
		I highly recommend you check out my mutt page, and my.muttrc, as I use mutt with procmail, and it really is the best way to handle mail.
		At it's simplest, procmail can be used to put email into different folders depending on where it came from, an invaluable aid to reading mailing lists.
		For each email, procmail will test it against each rule until one matches, and then process the action accordingly.

		Back to top Here's an example that I use: I do not have CGI access, so I have my web forms mailed to me and have procmail send them to the right programs, so that they are processed correctly.
		It's a good idea to put your spam killer last, because the whole point of it is to trash mail you don't recognise, and any mail that gets grabbed by the other rules will be mail that you recognise in some sense.
