FAQ
Message is frozen
Mail can't be delivered locally, check storage.
hostname --fqdn did not return a fully qualified name
fix /etc/hosts etc, but if hostname -f/--fqdn fails, run hostname mail.example.com and save yourself a lot of headache
Helo command rejected: need fully-qualified hostname

all relevant MX records point to non-existent hosts
This may mean the MX IP is a private one, in that case remove that IP/network from ignore_target_hosts
