So I rebooted my mail server, and now dovecot fails to start with: Stopping Dovecot Imap: [FAILED] Starting Dovecot Imap: Fatal: listen(::, 143) failed: Address already in use [FAILED]
What is listening on port 143? aka: netstat -tlnp | grep ':143 '
Nothing was listening on 143. The problem was that the default configuration of dovecot is for listening for ipv4 and ipv6. We had previously disabled ipv4 on the NIC and in the kernel, but not reloaded the settings in modprob.conf.
When we rebooted the server, ipv6 was therefore GONE. dovecot was trying to listed on 143 on both ipv4 and ipv6, not finding ipv6 and not starting.
adding "listen = *" to dovecot.conf (so that it only listens for ipv4) resovled the problem.
