Postfix
Postfix is a free open source mail transfer agent (MTA), a
computer program for the routing and delivery of email. It is intended
as a fast, easy-to-administer, and secure alternative to the
widely-used Sendmail MTA.
Postfix is the default MTA for a number of operating systems
such as Ubuntu.
Although IBM supported the Postfix development, it abstains
from control over its evolution.
Features include:
- Transport Layer Security (TLS)
- Delegation of SMTP policies to an external process (this
allows Greylisting) and advanced content filtering
- Different databases for maps: Berkeley DB, CDB, DBM, LDAP,
MySQL
and PostgreSQL
- mbox-style mailboxes, Maildir-style mailboxes, and virtual
domains
- Address rewriting (envelope and header), VERP, SMTP-AUTH
via SASL, and more
- Milter support compatible with Sendmail
milters
- Using Policyd-weight, can check e-mail headers against
various DNSBLs and for RFC compliance, and reject near-certain spam
ahead of receiving the body of the messages, lessening server load
