Hello, We are having an issue with messages sent out through Mailman server that don't reach a specific email domain. In the exim main log, we see these error messages repeatedly show up:
em...@thatdomain.com R=dnslookup T=remote_smtp defer (-53): retry time not reached for any host or em...@thatdomain.com R=dnslookup T=remote_smtp defer (110): Connection timed out Our Mailman server is not on any blacklist. What would likely be the issue here?
