Hi,
554 5.0.0 MX list for gonzo.domain.com. points back to master.domain.com 554 5.3.5 <homepage@xxxxxxxxxxxxxxxx>... Local configuration error
Does the RaQ (which runs as master.domain.com) know it has to accept mail for gonzo.domain.com? In other words: has gonzo.domain.com been added to class w of sendmail (/etc/sendmail.cw or /etc/mail/local-host-names [I don't run a RaQ and/or sendmail anymore, so I really can't tell])?
Good luck... Nico
