But other DD's can also only do a limited amount of research, the only way to really find out is asking a postmaster -- this isn't a prosecution, so 'evidence' is not needed, I'd say (though, a copy of one bounce message with full headers would be the minimum I'd expect, because otherwise debugging is close to impossible). In general, this failure means that for 4 consecutive days the a connection attempt that happens roughly every 8 hours fails (connection refused, a timeout, HELO refused, stuff like that). Are you sure that this condition can never have happened? I see you only have one MX, for increased reliability and for cases when for example there's a routing problem somewhere between master and that one single MX, add a backup MX. When an exim mailserver is really bogged down under mail load, attempts can be made even less often. > IIRC, when there are no prolonged connectivity > problems, the error message is characteristic of a broken Exim retry > configuration (no retry section at all, or something like that), but > master's configuration seems to be fine in this regard. > > The host mail.enyo.de had some intermittent connectivity problems > during the past few weeks (downtimes of about one hour every couple of > days, nothing which should cause Exim to run past its configured retry > limit).

I'd really look into a secondary MX, but if it's indeed only there two problems at the frequency you say, it shouldn't really be possible that this is the cause. > This problem has gained some unexpected urgency because I was kicked > off the PTS due to these bounces (I think so, I haven't been shown one > of the PTS bounces).

There is no automatic bounce handling for the PTS, that's still on the TODO... --Jeroen -- Jeroen van Wolffelaar [EMAIL PROTECTED] (also for Jabber & MSN; ICQ: 33944357) http://Jeroen.A-Eskwadraat.nl -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
