GNU Mailutils is a collection of mail-related utilities. At the core of Mailutils is libmailbox, a library which provides access to various forms of mailbox files (including remote mailboxes via popular protocols). It also provides support for parsing of RFC-822 style messages and MIME support.
Following is a short description of the mail utilities. All utilities share the same subset of command line options and use single configuration file, which allows to easily configure the package as a whole.
The Mailutils' imap4d
implements Internet Message Access Protocol, version 4rev1 as per RFC 2060.
It supports Namespace capability and GSSAPI authentication mechanism.
Pop3d
is a daemon implementing Post Office Protocol server.
Comsatd
is the program notifying users about incoming e-mail. Being
highly configurable, this implementation of comsatd gives the user full control
over the notification method. It also includes a protection mechanism
against some well-known comsatd attacks.
Mailutils provides mail delivery agents for local delivery and for remote delivery via SMTP protocol.
This program delivers mail to the local mailboxes. It supports per-user quotas on the mailbox size and provides hooks to run mail-filtering scripts before actual delivery. Such scripts may be written either in Sieve or in Scheme.
The mail.remote
is designed as a drop-in replacement
for /usr/lib/sendmail
to forward mail directly to an SMTP gateway.
This is an interface program used by GNU Emacs
rmail
module to read user's incoming mail. It contains a number
of improvements over the standard movemail
version while being
compatible with the existent rmail.el
.
The improved rmail.el
, taking advantage of all the features
provided by our movemail
should become available with the next
version of GNU Emacs. In the meanwhile its code is available from
Sergey Poznyakoff's
site.
The frm
command outputs headers from the selected
messages in a mailbox.
Mail
is a replacement for /bin/mail
and /bin/mailx
.
While being compatible with those, mail
understands various mailbox formats
(including remote mailboxes, via pop3 or imap4d protocol), provides extended line-editing
capabilities, is fully configurable and is able to decode MIME messages.
Messages
prints on standard output the number of messages
contained in each folder specified in command line. If no folders are
specified, it operates upon user's system mailbox.
Readmsg
extracts from the mailbox messages matching a given set
of criteria and prints their contents on the standard output.
This is a set of utilities compatible with MH Message Handling System.
While being backward compatible with both standard mh and nmh
,
our implementation of MH offers all the flexibility and power of GNU Mailutils.
It has been designed to interoperate flawlessly with
GNU Emacs MH-E interface. Newer
versions of MH-E provide support for extended features of GNU Mailutils MH.
Mailutils offers support for two mail processing languages: Sieve and Scheme.
Guimb stands for "Guile for MailBoxes". It is designed
to provide for mailboxes the same functionality that awk
provides
for text files. It processes mailboxes, applying the user-supplied Scheme programs
to each of them in turn and saves the resulting output in required mailbox format.
Mailutils provides two implementations of the Sieve language (RFC
3028): a standalone program sieve
, and
sieve.scm
-- a Sieve compiler written entirely in Scheme.
Both provide full support for the Sieve language with a set of
extensions.
Sieve
takes a Sieve script and applies it to the given mailbox.
Sieve.scm
translates a Sieve script into an equivalent
Scheme program and optionally applies it to the given set of
mailboxes. The produced Scheme program can be used as a plug-in filter
for mail.local
utility.
Language extensions, such as new tests, actions and comparators, can be easily added to both implementations.
GNU Mailutils can be downloaded from http://ftp.gnu.org/gnu/mailutils/ or one of the mirrors.
The latest stable release of GNU Mailutils is version 1.0, released on July 7, 2006.
