Email sends email to remote SMTP servers via the command line, which makes it useful in cron jobs. It will send to any RFC standard remote ESMTP server, and will allow you to encrypt, sign, and design your message on the fly. It has the capability to use signature files with dynamic options, address book functionality, and users can also attach pictures, binary files, documents, or whatever they want. It is completely compatible with GNUPG for encryption and signing, and is easy to configure and use.

Hotway is a POP3-HTTPMail gateway daemon. HTTPMail is an undocumented WebDAV-based protocol used by hotmail. This gateway allows *any* POP3 compatible email client to handle (download, delete, etc) messages on hotmail.com, msn.com and lycos mailboxes.
It goes in through the back door so that you don't have to worry about web interface changes.

Set of simple utilities for managing IMAP emails.

maildirproc is a program that processes one or several existing mail boxes in
the maildir format. It is primarily focused on mail sorting — i.e., moving,
copying, forwarding and deleting mail according to a set of rules. It can be
seen as an alternative to procmail, but instead of being a delivery agent
(which wants to be part of the delivery chain), maildirproc only processes
already delivered mail. And that's a feature, not a bug.

maildrop is a replacement for your local mail delivery agent. maildrop reads a
mail message from standard input, then delivers the message to your mailbox.
maildrop knows how to deliver mail to mbox-style mailboxes, and maildirs.
"maildir" is a mailbox format used by Courier and Qmail.

maildrop optionally reads instructions from a file, which describe how to
filter incoming mail. These instructions can direct maildrop to deliver the
message to an alternate mailbox, or forward it somewhere else. Unlike procmail,
maildrop uses a structured filtering language.

maildrop is written in C++, and is significantly larger than procmail. However,

pfqueue is an effort to give postqueue/mailq/postsuper/exim4 a console
(ncurses) interface: it won't add any particular functionality to those
provided with MTAs themselves, but will hopefully make them easier to use.
It's a real-time queue scanner, that shows per-queue lists of existing
messages; the messages can be shown, deleted, put on hold, released or
requeued.

Converts Outlook PST mailbox files into the standard mbox format.
