I can't get mail delivered to a specific domain. The messages just
stay in the queue.
DNS says
domain MX 0 host1
domain MX 10 host2
host1 says
520 Connection not authorised from this address.
qmail connects to host1 and says
deferral: Connected_to_N.N.N.N_but_greeting_failed./...
qmail seemingly never tries host2.
The administrators of domain says
- this setup is intentional (sort of firewall/spam control)
- why isn't your mailer using the second-best MX?
- others have reported this too. They use qmail too.
What's wrong here? The error code? qmail?
