What is Postfix?

Postfix, a mail server created by Wietse Venema at IBM research, serves as a practical alternative to the widely-used Sendmail program and is continuously updated and improved by Wietse in his role at Google. This powerful mail server is compatible with a range of UNIX systems, such as AIX, BSD, HP-UX, IRIX, LINUX, MacOS X, Solaris, and Tru64 UNIX, and operates with the requirements of ANSI C, a POSIX.1 library, and BSD sockets. Focused on speed, user-friendly administration, and robust security, Postfix presents a user interface similar to that of Sendmail, but its underlying framework is fundamentally different. It boasts several advanced features, including support for multiple SMTP deliveries over a single TLS-encrypted connection by utilizing tlsproxy(8) and scache(8) services and the capability to execute MySQL stored procedures. Furthermore, Postfix includes a gradual degradation feature that enables the daemon to log warnings and persist in functioning even when minor service issues arise, avoiding abrupt terminations due to fatal errors. Additionally, it can activate the execute bit on a queue file, a crucial aspect since failing to do so could hinder successful mail delivery. Collectively, these features establish Postfix as an adaptable and reliable option for effective mail server management, making it a favored choice among administrators seeking a robust solution for their email needs.
