Operating System Compatibility
Dovecot is commonly used with Linux, Solaris, FreeBSD, OpenBSD, NetBSD and Mac OS X. The following operating systems have also worked at least at some point in Dovecot's existence:
- BSD/OS 4.2
- AIX 4.3
- HP-UX 11.11
- Tru64 ?.?
UnixWare 7.1.4
- IRIX 6.5 compiles, but SCM_RIGHTS seems to be broken.
- Cygwin apparently doesn't work nowadays.
- MidnightBSD (ports)
There is one slightly problematic feature that Dovecot requires: SCM_RIGHTS. It is used for privilege separation. If it is not supported, you can still use inetd and mailfront, which executes Dovecot's IMAP or POP3 binary.
Compilers
Dovecot should compile with any ANSI-C99 compiler. Dovecot has been known to compile (at least once in its lifetime) with the following compilers:
