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.
