Any thought how I can troubleshoot this?
map out your traffic one step at a time.
connect with
openssl s_client
curl
from an external server, and manually exec an smtp transaction.
&/or, less convenietly, (re)send mail from an external mail account,
gmail or somesuch.
exec tcpdump on each of your listening interfaces/ports, and turn on
verbose logging on all your server listeners (named, postfix &
dovecot), and identify where the traffic flows to, and where it stops.
