Newsgroups: comp.sources.misc From: Stephen R. van den Berg <berg@messua.informatik.rwth-aachen.de> Subject: v20i089: procmail - mail processing program v2.10, Part01/03 Message-ID: <csm-v20i089=procmail2.10.202848@sparky.imd.sterling.com> X-Md4-Signature: 18c5d251cd673f6c2ac0d0e8ada39c37 Date: Wed, 10 Jul 1991 01:32:51 GMT Approved: kent@sparky.imd.sterling.com Submitted-by: Stephen R. van den Berg <berg@messua.informatik.rwth-aachen.de> Posting-number: Volume 20, Issue 89 Archive-name: procmail2.10/part01 Supersedes: procmail: Volume 20, Issue 49-51,68 Environment: UNIX, sendmail, smail, MMDF The procmail mail processing program. (v2.10 1991/07/08) Can be used to create mail-servers, mailing lists, sort your incoming mail into separate folders/files (real convenient when subscribing to one or more mailing lists), preprocess your mail, or selectively forward certain incoming mail automatically to someone. For a more extensive feature list, see below. -- Sincerely, berg@messua.informatik.rwth-aachen.de Stephen R. van den Berg. berg@physik.tu-muenchen.de ---------------------- A recent version can be picked up at various comp.sources.misc archives. The latest version can be obtained directly from the ftp-archive at: amaru.informatik.rwth-aachen.de (137.226.112.31) as compressed tar file: pub/unix/procmail.tar.Z or in compressed shar format: pub/unix/procmail.0?.Z ---------------------- Feature summary for procmail: + It's small + Very easy to install + Simple to maintain and configure because all you need is actually only ONE executable (procmail) and ONE configuration file (.procmailrc) + Uses *your* (i.e. easily configurable) favourite regular expression syntax + Allows for very-easy-to-use yes-no decisions on where the mail should go + Filters, delivers and forwards mail *reliably* + Provides a stable and guaranteed environment for any programs or shell scripts you may wish to start upon mail arrival + Is designed for reliability, once procmail gets hold of your mail you can consider it delivered + Is event driven (i.e. gets invoked automagically when mail arrives) + Performs heroically under even the worst conditions (file system full, out of swap space, process table full, file table full, missing support files, unavailable executables, denied permissions) and tries to deliver the mail somehow anyway (it usually succeeds were other programs would have given up) + procmail is the closest you can get to a program that outlives the swapper :-) + Absolutely undeliverable mail (after trying every trick in the book) will bounce back to the sender + Does not use *any* temporary files + Is explicitly designed to work under NFS as well + Performs more reliable mailbox locking than most other mailers (especially across NFS, DON'T use NFS mounted mailboxes WITHOUT installing procmail, you may use valuable mail one day) + Supports four mailfolder standards: single file folders (standard and nonstandard VNIX format), directory folders (AMS -- Andrew Mail System) that contain one file per message, or the similar MH directory folders (numbered files) + Variable assignment and substitution is a extremely complete subset of the standard /bin/sh syntax + Provides a mail log file, which logs all mail arrival, shows in summary whence it came from, what it was about, where it went (what folder) and how long (in bytes) it was + Uses this log file to display a wide range of diagnostic and error messages (if something went wrong) + Processed mail can contain arbitrary 8-bit characters (including '\0'); i.e. binary mailings can be processed if the rest of the mailing system knew how to handle them too + It has a man page (boy, does *it* have a man page) + procmail can be used as a local delivery agent (substitute for /bin/mail) + It runs on virtually all (old and future) operating systems which names start with a 'U' or end in an 'X' :-) (i.e. extremely portable code) + Works with (among others?) sendmail, smail and MMDF Feature summary for formail: + Can generate auto-reply headers + Can force mail into mailbox format (so that you can process it with standard mail programs) + Can split up mailboxes into the individual messages + Can split up digests into the individual messages + Can split up saved articles into the individual articles Feature summary for lockfile: + Provides NFS-secure lockfiles to shell script programmers ---- Cut Here and feed the following to sh ---- #!/bin/sh # This is procmail, a shell archive (produced by shar 3.49) # To extract the files from this archive, save it to a file, remove # everything above the "!/bin/sh" line above, and type "sh file_name". # # made 07/08/1991 14:38 UTC by berg@messua.informatik.rwth-aachen.de # Source directory /tmp_mnt/tmp/.am/baghira/berg # # existing files will NOT be overwritten unless -c is specified # # This shar contains: # length mode name # ------ ---------- ------------------------------------------ # 2178 -rw-r--r-- procmail/examples/2procmailrc # 392 -rw-r--r-- procmail/examples/2rmail # 1477 -rw-r--r-- procmail/examples/3procmailrc # 757 -rw-r--r-- procmail/examples/3rmail # 2883 -rw-r--r-- procmail/examples/advanced # 37 -rw-r--r-- procmail/examples/forward # 400 -rw-r--r-- procmail/examples/1rmail # 602 -rw-r--r-- procmail/examples/1procmailrc # 47 -rw-r--r-- procmail/include/stdlib.h # 16 -rw-r--r-- procmail/include/sys/utsname.h # 252 -rw-r--r-- procmail/include/sysexits.h # 31 -rw-r--r-- procmail/include/stddef.h # 48 -rw-r--r-- procmail/include/string.h # 31 -rw-r--r-- procmail/include/unistd.h # 20225 -rw-r--r-- procmail/man/procmail.1 # 3441 -rw-r--r-- procmail/man/formail.1 # 2758 -rw-r--r-- procmail/man/lockfile.1 # 2029 -rw-r--r-- procmail/includes.h # 3739 -rw-r--r-- procmail/README # 1652 -rw-r--r-- procmail/STYLE # 1610 -rw-r--r-- procmail/common.c # 1788 -rw-r--r-- procmail/exopen.c # 1824 -rw-r--r-- procmail/Manifest # 2723 -rw-r--r-- procmail/lockfile.c # 7495 -rw-r--r-- procmail/goodies.c # 13100 -rw-r--r-- procmail/procmail.c # 7135 -rw-r--r-- procmail/nonint.c # 9902 -rw-r--r-- procmail/retint.c # 188 -rw-r--r-- procmail/shell.h # 3986 -rw-r--r-- procmail/INSTALL # 1939 -rw-r--r-- procmail/Makefile # 3012 -rw-r--r-- procmail/autoconf # 170 -rw-r--r-- procmail/exopen.h # 9280 -rw-r--r-- procmail/formail.c # 2781 -rw-r--r-- procmail/config.h # 1980 -rw-r--r-- procmail/procmail.h # 7939 -rw-r--r-- procmail/HISTORY # 3092 -rw-r--r-- procmail/FEATURES # # ============= procmail/examples/2procmailrc ============== if test ! -d 'procmail';

According to the processing recipes in this file, Xthe mail message that just arrived gets distributed into the right folder X(and more). X.Ss Defaults X.Tp 2.2i X.B "USER, HOME and SHELL" XYour (the recipient's) defaults X.Tp X.B SHELLMETAS X"'`&#()[]*?|<>~;!\\ X.Tp X.B SHELLFLAGS X-c X.Tp X.B MAILDIR X$HOME X.Tp X.BR DEFAULT X$MAILDIR/.mailbox X.Tp X.B ORGMAIL X/var/spool/mail/$USER X.Tp X.B MSGPREFIX Xmsg. X.Tp X.B GREP X/usr/bin/egrep X.Tp X.B SENDMAIL X/usr/lib/sendmail X.Tp X.B LOCKEXT X\&.lock X.Ss Environment X.LP XBefore you get lost in the multitude of environment variables, keep in mind Xthat all of them have reasonable defaults. X.Tp 1.2i X.B MAILDIR XCurrent directory while procmail is executing (that means that all paths Xare relative to $MAILDIR). X.Tp X.B DEFAULT XDefault X.B mailbox Xfile (if not told otherwise, procmail will dump mail in this mailbox). X.Tp X.B MSGPREFIX XFilename prefix that is used when delivering to a directory (not used when Xdelivering to a MH directory). X.Tp X.B LOGFILE XAll incoming messages will be logged here with their `From ' and `Subject:' Xlines in the header, and an additional line specifying what folder it Xfinally went to and how long (in bytes) the message was. This file will Xalso contain any error or diagnostic messages from procmail X(normally none :-) or any other programs started by procmail. If this file Xis not specified it defaults to X.BR /dev/null . X.Tp X.B LOG XAnything assigned to this variable will be echoed in $LOGFILE. X.Tp X.B ORGMAIL XUsually the system mailbox (\fBOR\fPi\fBG\fPinal \fBMAIL\fPbox). If, for Xsome obscure reason (like `\fBfilesystem full\fP') the mail could not be Xdelivered, then this mailbox will be the last resort. If procmail Xfails to save the mail in here (deep, deep trouble :-), then the mail Xwill bounce back to the sender. X.Tp X.B LOCKFILE XGlobal semaphore file. If this file already exists, procmail Xwill wait until it has gone before proceeding, and will create it itself X(cleaning it up when ready, of course). If more than one X.I lockfile Xare specified, then the previous one will be removed before trying to create Xthe new one. X.Tp X.B LOCKEXT XDefault extension that is appended to a destination file to determine Xwhat local X.I lockfile Xto use (only if turned on, on a per-recipe basis). X.Tp X.B LOCKSLEEP XNumber of seconds procmail will sleep before retrying on a X.I lockfile X(if it already existed); if not specified, it defaults to eight seconds. X.Tp X.B LOCKTIMEOUT XNumber of seconds that have to have passed since a X.I lockfile Xwas last modified/created before procmail decides that this must be an Xerroneously leftover lockfile that can be removed by force now. If zero, Xthen no timeout will be used and procmail will wait forever until the Xlockfile is removed; if not specified, it defaults to one hour. This variable Xis usefull to prevent indefinite hangups of X.BR sendmail /procmail. X.Tp X.B TIMEOUT XNumber of seconds that have to have passed before procmail decides that Xsome child it started must be hanging. The offending program will receive Xa SIGTERM from procmail, and processing of the rcfile will continue. If zero, Xthen no timeout will be used and procmail will wait forever until the child Xhas terminated; if not specified, it defaults to 59 minutes. X.Tp X.B HOST XIf this is not the X.I hostname Xof the machine, processing of the current X.I rcfile Xwill immediately cease. If other rcfiles were specified on the Xcommand line, processing will continue with the next one. If all rcfiles Xare exhausted, the program will terminate, but will not generate an error X(i.e. to the mailer it will seem that the mail has been delivered). X.Tp X.B UMASK XThe name says it all (if it doesn't, then forget about this one :-). It Xis taken as an X.B octal Xnumber. If not specified, it defaults to 077. X.Tp X.B GREP XThe program that gets called for parsing regular expressions. X.br XIt is called as: "$GREP" -e "$*" [-i]; X.Tp X.B SHELLMETAS XIf any of the characters in SHELLMETAS appears in the line specifying Xa filter or program, the line will be fed to $SHELL Xinstead of being executed directly. X.Tp X.B SHELLFLAGS XAny invocation of $SHELL will be like: X.br X"$SHELL" "$SHELLFLAGS" "$*"; X.Tp X.B SENDMAIL XIf you're not using the X.I forwarding Xfacility don't worry about this one. It specifies the program being Xcalled to forward any mail. X.br XIt gets invoked as: "$SENDMAIL" $@; X.Tp X.B NORESRETRY XNumber of retries that are to be made if any `\fBprocess table full\fP', X`\fBfile table full\fP', `\fBout of memory\fP' or X`\fBout of swap space\fP' error should occur. If this number is negative, Xthen procmail will retry indefinitely; if not specified, it defaults to two Xtimes. The retries occur with a $SUSPEND second interval. The idea behind Xthis is, that if the X.I swap X.I space Xhas been exhausted or the X.I process X.I table Xis full, usually several other programs will either detect this Xand abort or crash 8-), and thereby freeing valuable X.I resources Xfor procmail. X.Tp X.B SUSPEND XNumber of seconds that procmail will pause if it has to wait for something Xthat is currently unavailable (memory, fork, etc.); if not specified, it will Xdefault to 16 seconds. See also: X.BR LOCKSLEEP . X.Tp X.B LINEBUF XLength of the internal line buffers, cannot be set smaller than 128. All lines Xread from the rcfile X.RI ( not Xthe mail itself, which can have arbitrary line lengths, or could be a binary Xfile for that matter) should not exceed $LINEBUF characters before and after Xexpansion. If not specified, it defaults to 2048. X.Sh OPTIONS X.Tp 0.5i X.B \-d XTurns on debugging mode. procmail will log every little thing it Xdoes to $LOGFILE. Very usefull if you wonder if procmail parses Xyour rcfile file right. X.Tp X.B \-p XPreserve any old environment. Normally procmail clears the environment Xupon startup. However, in any case: any default values will override any Xpreexisting environment variables, i.e. procmail will not pay any attention Xto any predefined environment variables, it will happily overwrite them Xwith his own defaults. X.Tp X.B \-v Xprocmail will print its version number and exit. X.Sh ARGUMENTS X.LP XAny arguments containing an '=' are considered to be environment variable Xassignments, they will X.I all Xbe evaluated after the default values have been Xassigned and before the first rcfile is opened. X.LP XAny other arguments are presumed to be rcfile paths (absolute or relative to X$HOME); procmail will start with the first one it finds on the command line. XThe following ones will only be parsed if the preceding ones have a not Xmatching HOST-directive entry, or in case they should not exist. X.LP XIf no rcfiles are specified, it looks for X.BR $HOME/.procmailrc . XIf not even that can be found processing will continue according to Xthe default settings of the environment variables and the ones specified Xon the command line. X.Sh "RCFILE FORMAT" X.LP XEnvironment variable X.B assignments Xand X.B recipes Xcan be freely intermixed in the rcfile. If any environment variable has Xa special meaning to procmail, it will be used appropiately the moment Xit is parsed. (i.e. you can change the current directory whenever you Xwant by specifying a new X.BR MAILDIR , Xswitch lockfiles by specifying a new X.B LOCKFILE X(usually one won't need this particular application though), change Xthe umask at any time, etc., the possibilities are endless :-). X.LP XThe assignments and substitutions of these environment variables are handled Xexactly like in X.BR sh (1) X(that includes all possible quotes and escapes), Xwith the added bonus that blanks around the '=' sign are ignored and that, Xif an environment variable appears without a trailing '=', it will be Xremoved from the environment. X.LP X.Ss Comments XA word beginning with # and all the following characters up to a NEWLINE Xare ignored. X.Ss Recipes X.LP XA line starting with ':' marks the beginning of a recipe. It has the Xfollowing format: X.LP X: X.RI [ " number " ] X.RI [ " options " ] X.RI "[ : [" " locallockfile " "] ]" X.LP XThe X.I number Xis optional (defaults to 1) and specifies the number of conditionals Xfollowing this line. Conditionals are complete lines that are passed on to X$GREP X.BR literally . XIf a conditional starts with an '!', the condition is inverted. If you really Xwant the conditional to start with an '!', precede the '!' by a '\\'. XConditionals are anded; if X.I number Xis zero, then the condition is always true and no conditionals are expected Xnext. X.LP X.I Options Xcan be any of the following (don't insert spaces in between the options): X.Tp 0.5i X.B H XFeed the header to $GREP (default) X.Tp X.B B XFeed the body to $GREP X.Tp X.B D XTell $GREP to distinguish between upper and lower case (defaults to ignoring Xcase) X.Tp X.B A XThis recipe will depend on the last recipe without the 'A' option. This Xallows you to chain actions that depend on a common condition. The number Xof conditionals that are expected to follow default to none. X.Tp X.B h XFeed the header to the pipe (default) X.Tp X.B b XFeed the body to the pipe (default) X.Tp X.B f XConsider the pipe as a filter (ignored if a file) X.Tp X.B c XContinue processing rcfile even if this recipe matches (not needed if 'f' Xspecified) X.Tp X.B w XWait for the filter or program to finish and check its exitcode (normally Xignored); if the filter is unsuccessfull, then the text will Xnot have been filtered. This option is also recommended if you specified any X.I locallockfile Xon this recipe. X.Ss "Local lockfile" X.LP XIf you put a second ':' on the first recipe line, then procmail will use a X.I locallockfile X(for this recipe only). You optionally can specify the locallockfile Xto use; if you don't however, procmail Xwill use the filename specified as the destination (or the filename Xfollowing the first '>>') and will append $LOCKEXT to it. X.Ss "Recipe destination" X.LP XThe next line can start with the following characters: X.Tp X.B ! XForwards to all the specified mail addresses. X.Tp X.B | XStarts the specified program, possibly in $SHELL if any Xof the characters $SHELLMETAS are found (that means comments normally force Xthis line to be processed by the shell). X.LP XAnything else will be taken as a mailbox name (either a filename or a Xdirectory, absolute or relative to the current directory (see $MAILDIR)). XIf it is a filename (or nonexistent), the mail will be appended to it. If Xit is a directory, the mail will be delivered to a newly created, guaranteed Xto be unique, file named $MSGPREFIX* in the specified directory. If the Xdirectory name ends in "/.", then this directory is presumed to be a MH Xfolder; i.e. procmail will use the lowest number it finds available.

That also means that any locallockfile on this Xrecipe might get removed X.I before Xthe program has terminated.

Deadlocks can be broken by proper use of X.BR LOCKTIMEOUT . X.LP XAny default values that procmail has for some environment variables will X.B always Xoverride the ones that were already defined. If you really want to Xoverride the defaults, you either have to put them in the X.B rcfile Xor in the command line as arguments.

X.LP XIn the unlikely event that you absolutely need to kill Xprocmail before it has finished, first try and use Xthe regular kill command X.RB ( SIGTERM ), Xotherwise some X.I lockfiles Xmight not get removed. X.Sh BUGS X.LP XThe only substitutions of environment variables that can be handled by Xprocmail itself are of the type $name, ${name}, $$ and $-; whereas $- will Xbe substituted by the name of the last folder delivered to. X.LP XAfter a lockfile is removed by force, a suspension of $SUSPEND seconds Xis taken into account, in order to prevent the inadvertent immediate removal Xof any newly created lockfile by another program. X.LP XA line buffer of length $LINEBUF is used when processing the X.IR rcfile , Xany expansions X.B have Xto fit within this limit; if they don't, behaviour is undefined. X.LP Xprocmail uses the regular kill command X.RB ( SIGTERM ), Xto terminate any runaway filter, but it does not check if the filter responds Xto that signal and it only sends it to the filter itself, not to any of its Xchildren. X.LP XIf the global lockfile has a X.I relative Xpath, and the current directory Xis not the same as when the global lockfile was created, then the global Xlockfile will not be removed if procmail exits at that point (remedy: Xuse X.I absolute Xpaths to specify global lockfiles). X.LP XSome braindamaged mailers want all lines that start with `From ' to be escaped, Xprocmail only escapes those that could really be dangerous; to support those Xother mailers you should consider using X.BR formail (1) Xas a filter for all your mail. X.Sh MISCELLANEOUS X.LP XAny program executed from within procmail will be searched for along the PATH. XIt is advisable however, to Xspecify an absolute path for $GREP, because it gets executed fairly often. X.LP XWhitespace is ignored in the rcfile, except between the flags and on the Xlines that are fed to $GREP; i.e. you can indent everything except the Xcondition lines. X.LP XIf the regular expression starts with `\fB^TO\fP' it will be substituted by X`\fB^(To|Cc|Apparently-To):.*\fP', which should catch all destination Xspecifications. X.LP XAny lines in the body of the message that look like postmarks are prepended Xwith '>' (disarms bogus mailheaders). The regular expression that is used Xto search for these postmarks is: X.RS X\\n\\nFrom +[^\\t\\n ]+ +[^\\n\\t] X.RE X.LP XShould the uid procmail is running under, have no corresponding /etc/passwd Xentry, then HOME will default to /tmp, USER will default to #uid. X.LP XWhen delivering to directories (or to MH folders) you X.B don't Xneed to use lockfiles to prevent several concurrently running procmail Xprograms from messing up. X.LP XDelivering to MH folders is slightly more time consuming than delivering Xto normal directories or mailboxes, because procmail has to search for Xthe first available number (instead of having the filename immediately Xavailable).

X.LP XSince flags can occur anywhere on the command line, any filename starting Xwith a '-' has to be preceded by './'. X.LP XThe number of X.I retries Xis global. That is, it is not reset when a new file is being created. XIt can, however, be reset by specifying X.RI \-r newretries Xafter every file on the command line. X.LP Xlockfile performs the locking in an NFS-secure way.
