GNU Mailutils – a rich and powerful protocol-independent mail framework. It contains a series of useful mail libraries, clients, and servers.
These are the primary mail utilities for the GNU system. The central library is capable of handling electronic mail in various mailbox formats and protocols, both local and remote. Specifically, this project contains a POP3 server, an IMAP4 server, and a Sieve mail filter. It also provides a POSIX “mailx” client and a collection of other handy tools.
Mailutils is oriented toward three kinds of audiences: regular users, system administrators, and developers of email-handling software.
Regular users will find here an implementation of the traditional UNIX mail reader mail, command line utilities, such as frm, messages, readmsg, and sieve — a flexible utility for filtering the incoming mail.
A special feature of Mailutils is an implementation of the MH Message Handling System, which combines a power of the UNIX philosophy with a flexibility of Mailutils libraries, thus allowing to easily incorporate mail from remote mailboxes.
For system administrators, Mailutils provides a set of daemons for delivering and reading electronic mail, including pop3d, imap4d, local mail transport daemon lmtpd, and a universal mail delivery agent, mda, and LMTP daemon.
