I have a problem with the smtp proxy. some outgoing mails are not being delivered for some reason.
first there's a message like this :
----------------------------------------------
me@mydomain.com -> user@outside.com
Subject: test
Content Scanner: [message processed ok]
Cause: 2003-06-23 11:48:42 user@outside.com R=dnslookup T=remote_smtp defer (-53): retry time not reached for any host
------------------------------------------------------
and then, after a while it says :
-------------------------------------------------------
user@outside.com R=dnslookup T=remote_smtp defer (104): Connection reset by peer: mail.outside.com [194.132.1.3]
-------------------------------------------------------
(I made these addresses up, that's not the real ones...)
the odd thing is : the problem seems to appear when sending mails to certain domains, but : some mails to these domains go through, others don't.
does anyone have a clue what's going on here ? any help on this would be very much appreciated.
