opensmtpd

secure, reliable, lean, and easy-to configure SMTP server

The OpenSMTPD server seeks to be * as secure as possible, and uses privilege separation to mitigate possible security bugs * as reliable as possible: any accepted email must not be lost * lean: it covers typical usage cases instead of every obscure one * easy to configure, with a configuration syntax reminiscent of the OpenBSD Packet Filter's (PF) * fast and efficient: it can handle large queues with reasonable performance

sendmail

powerful, efficient, and scalable Mail Transport Agent (metapackage)

Sendmail is an alternative Mail Transport Agent (MTA) for Debian. It is suitable for handling sophisticated mail configurations, although this means that its configuration can also be complex. Fortunately, simple things can be done easily, and complex things are possible, even if not easily understood ;) Sendmail is the *ONLY* MTA with a Turing complete language to control *ALL* aspects of delivery! Sendmail provides Security and SPAM/UCE/UBE protection via several means. Sendmail includes *no* Mail User Agents (MUA), you'll have to pick from the plethora of available MUAs (mutt, vm, etc.) This package supports REGEX, DB, NIS, NIS+, LDAP, DNS maps, and has enabled TCPWrappers, IPv6, LockFile, SMTP AUTH(SASL), STARTTLS(SSL). This package is to make installation/upgrading easier (Do NOT delete it)
