Postfix is a hugely-popular Mail Transfer Agent (MTA) designed to determine routes and send emails. This cross-platform server is open-source, free, and suitable for installation on the majority of UNIX-like operating systems.
Numerous client and server programs make up Postfix: the latter tend to run in the backend, while user or administrator programs utilize the former. Postfix’s structure is modular: it comprises various small, independent executables. Different parameters, features, and options are available, too.
Another key aspect of Postfix is that it was created to overcome those drawbacks seen in Sendmail. A solid configuration keeps Postfix user data secure from leakage, abuse, and spam.
Postfix includes a cutting-edge queue manager capable of handling queues in a faster, smoother way. That’s why a number of administrators cite Postfix’s higher efficiency compared to Sendmail, even with high loads.
With Postfix, you can expect a significant degree of flexibility and simple administration, which makes it easier for beginners to set up than alternative MTA options. On top of this, Postfix offers support for Sendmail’s command line interface. It’s also compatible with a variety of Sendmail’s mail filters.
