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.
