Postfix is an alternative to the widely-used Sendmail program.
Postfix is an alternative to the widely-used Sendmail program.Postfix attempts to be fast, easy to administer, and secure, while at the same time being sendmail compatible.
Postfix runs on AIX, BSD, HP-UX, IRIX, LINUX, MacOS X, Solaris, Tru64 UNIX, and other UNIX systems. It requires ANSI C, a POSIX.1 library, and BSD sockets.
The Postfix mail queue requires that: - the file system can rename a file to a near-by directory without changing the file's inode number, and that
- mail is safely stored after fsync() (of that file, not its parent directory) returns successfully, even when that file is renamed to a near-by directory at some later point in time.
- Maildir delivery also requires that a file can be hard linked between different near-by directories. Mailbox delivery introduces no additional requirements beyond what is already needed for Postfix queues.
