- Feature summary for procmail:
- + It's less filling (i.e. small)
- + Very easy to install (rated PG6 :-)
- + Simple to maintain and configure because
- all you need is actually only ONE executable (procmail)
- and ONE configuration file (.procmailrc)
- + Is event driven (i.e. gets invoked automagically when mail arrives)
- + Does not use *any* temporary files
- + Uses standard egrep regular expressions
- + It poses a very low impact on your system's resources
- (it's 1.4 times faster than the average /bin/mail in user-cpu
- time)
- + Allows for very-easy-to-use yes-no decisions on where the mail
- should go (can take the size of the mail into consideration)
- + Also allows for neural-net-type weighted scoring of mails
- + Filters, delivers and forwards mail *reliably*
- + Provides a reliable hook (you might even say anchor :-) for any
- programs or shell scripts you may wish to start upon mail arrival
- + 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
- + Absolutely undeliverable mail (after trying every trick in the book)
- will bounce back to the sender (or not, your choice)
- + Is one of the few mailers to perform reliable mailbox locking across
- NFS as well (DON'T use NFS mounted mailboxes WITHOUT installing
- procmail; you may lose valuable mail one day)
- + Supports four mailfolder standards: single file folders (standard
- and nonstandard VNIX format), directory folders that contain one file
- per message, or the similar MH directory folders (numbered files)
- + Native support for /var/spool/mail/b/a/bar type mailspools
- + Variable assignment and substitution is an 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, 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)
- + Does not impose *any* limits on line lengths, mail length (as long
- as memory permits), or the use of any character (any 8-bit character,
- including '\0' is allowed) in the mail
- + It has man pages (boy, does it have man pages)
- + Procmail can be used as a local delivery agent with comsat/biff
- support (*fully* downwards compatible with /bin/mail); in which case
- it can heal your system mailbox, if something messes up the
- permissions
- + Secure system mailbox handling (contrary to several well known
- /bin/mail implementations)
- + Provides for a controlled execution of programs and scripts from
- the aliases file (i.e. under defined user ids)
- + Allows you to painlessly shift the system mailboxes into the
- users' home directories
- + 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; POSIX, ANSI C and K&R conforming)
- + Is clock skew immune (e.g. in the case of NFS mounted mailboxes)
- + Can be used as a general mailfilter for whole groups of messages
- (e.g. when called from within sendmail.cf rules)
- + Works with (among others?) sendmail, ZMailer, smail, MMDF and
- mailsurr
-
- Feature summary for formail:
- + Can generate auto-reply headers
- + Can convert mail into standard 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
- + Can do simple header munging/extraction
- + Can extract messages from mailboxes
- + Can recognise duplicate messages
-
- Feature summary for lockfile:
- + Provides NFS-secure lockfiles to shell script programmers
- + Gives normal users the ability to lock their system mailbox,
- regardless of the permissions on the mail-spool directory
