* Postfix – A fast, secure, easy-to-administer MTA for Linux / Unix systems

In the mid 2000s, UUCP over TCP / IP ( often encrypted, using the SSH protocol ) was proposed for use when a computer does not have any fixed IP addresses but is still willing to run a standard mail transfer agent ( MTA ) like Sendmail or Postfix.

Dr. Wietse Zweitze Venema ( born 1951 ) is a Dutch programmer and physicist best known for writing the Postfix email system.

* Postfix source code patch may be necessary for RFC 6531 UTF-8 header support.

Milter ( portmanteau for mail filter ) is an extension to the widely used open source mail transfer agents ( MTA ) Sendmail and Postfix.

It was originally designed to be a drop-in replacement for qmail-smtpd, the SMTP component of qmail, and it is now also compatible with Postfix, Exim, sendmail and virtually any software that " speaks SMTP ".

Postfix is often combined with other software, for spam / virus filtering ( e. g., Amavisd-new ), message store access ( e. g., Dovecot ), and perhaps complex SMTP-level access policies ( e. g., policyd-weight or greylisting ).

Postfix implements a limited number of features in the MTA itself, and relies on third-party extensions for the rest.

Only a small number of Postfix daemons interact with users through two small " gate " programs for mail submission and for queue status information.

Conceptually, Postfix manages pipelines of processes that pass the responsibility for message delivery and error notification from one process to the next.

More complex Postfix implementations include integration with ( for example ) SpamAssassin and support for multiple ( virtual ) domain names, where data in databases such as MySQL can drive complex configurations.

Many common network services are provided such as NTP, SNMP, web server ( Apache ), mail server ( Postfix and Cyrus ), LDAP ( OpenLDAP ), AFP, and print server.

In UNIX and UNIX-like environments OTRS works closely with system programs like the mail transfer agent Postfix or the mail filter procmail.

Postfix notation makes the language easier to parse and extend ; Forth's flexibility makes a static BNF grammar inappropriate, and it does not have a monolithic compiler.

Some directory operations ( including < tt > unlink </ tt >( 2 )) are not synchronous on ReiserFS, which can result in data corruption with applications relying heavily on file-based locks ( such as mail transfer agents qmail and Postfix ) if the machine halts before it has synchronized the disk.

More recent surveys have suggested a decline, with 29. 4 % of mail servers in August 2007 detected as running Sendmail in a study performed by E-Soft, Inc. Sendmail is trailed by Microsoft Exchange Server, Exim, and Postfix ; these four being the only mail servers with more than 10 % of the total.

Some servers ( such as Sendmail and Postfix 2. 1 or later ) will attempt the next-furthest MX server after some types of temporary delivery failures, such as greeting failures.

Other servers ( such as qmail and Postfix 2. 0 or earlier ) will only use more distant MX records if the servers specified in the shortest-distance MX records could not be contacted at all.

* Many MTAs like Exim, Sendmail, and Postfix can be configured to absolutely block or ( less commonly ) to accept email based on a DNSBL listing.

Unlike qmail, Postfix, and ZMailer, Exim does not have a central queue manager ( i. e. an equivalent of qmail-send, qmgr, or scheduler ).

It was a hardened and secure OS, meaning that non-essential services and binaries are not installed, while UNIX staples like Sendmail are replaced by programs like Postfix.

* Postfix notation, a way of writing algebraic and other expressions.

It works with Unix style mail servers such as Postfix, Sendmail and qmail.

Postfix conditional testing may be accomplished by using the IFT (" if-then ") and IFTE (" if-then-else ") functions.

The Postfix mail transfer agent operates as a pipeline of individually-chrooted helper programs.
