Description

We regularly get a chunk of undeliverable e-mails to the hostmaster address:

  • <>: Sender address rejected: Domain not found (in reply to RCPT TO command)
  • <>: Sender address rejected: Domain not found (in reply to RCPT TO command)
  • pumbaa.documentfoundation.org[2a01:4f8:150:4343::2]:25: Network is unreachable (from antares)
  • pumbaa.documentfoundation.org[2a01:4f8:150:4343::2]:25: Network is unreachable (from berta)
  • <>: Sender address rejected: Domain not found (in reply to RCPT TO command)
  • <>: Sender address rejected: Domain not found (in reply to RCPT TO command)
  • <>: Sender address rejected: Domain not found (in reply to RCPT TO command)
  • <> (expanded from <root>): connect to 127.0.0.1[127.0.0.1]:10026: Connection refused (amavis doesn't seem to start)

Rather than creation exceptions on pumbaa, I prefer if we fix the issues on the machines directly.
Note that there might be some heavy mail backlog on the sending machines, so check postqueue before fixing - we once got blacklisted as a zillion of preserved mails were sent at once.

In today's mail, I spotted

  • antares
  • pollux

Can you give a quick update which boxes have been fixed and which still need fixing?

#5 Updated by Guilhem Moulin 5 months ago

What needs fixing with these two is the missing hostnames (mail.tdf rejects the message because the domain part of the envelope sender address doesn't have an A record). I'm waiting for the smarthost to fix these properly (there will be a secure link between each client and the smarthost so we can skip postconf's reject_unknown_sender_domain; and the smarthost should then rewrite the envelope sender address to be internet routable.)

Other boxes should be fixed.

What needs fixing with these two is the missing hostnames (mail.tdf
rejects the message because the domain part of the envelope sender
address doesn't have an A record). I'm waiting for the smarthost to fix
these properly (there will be a secure link between each client and the
smarthost so we can skip postconf's |reject_unknown_sender_domain|; and
the smarthost should then rewrite the envelope sender address to be
internet routable.)

Sounds sensible.

Other boxes should be fixed.

Thanks!
