Hi Guys,

Have an outgoing message which courier is now close on 40 hours trying to send, got the following logging:

Jan 23 23:00:37 webmail courierd: started,id=002AC436.4794FC14.0000462B, from=<$us...@cwisl.com>, module=esmtp, host=studioalp.it, addr=$us...@studioalp.it

Jan 23 23:05:37 webmail courieresmtp: id=002AC436.4794FC14.0000462B, from=<$us...@cwisl.com>, addr=<$us...@studioalp.it>: Connection refused

Jan 23 23:05:37 webmail courieresmtp: id=002AC436.4794FC14.0000462B, from=<$us...@cwisl.com>, addr=<$us...@studioalp.it>,status: deferred

if I dig the mx for studioalp.it I get:

;; ANSWER SECTION: studioalp.it. 66382 IN MX 10 mail.studioalp.it. studioalp.it. 66382 IN MX 20 mail2.mdsnet.it.

That says to me that courier is trying to deliver this message to host studioalp.it even though its not listed as a mail exchanger for the domain.

Is it possible to zap couriers cache of mx lookups, or how do I address this error. If I manually smtp to the target address to one of the listed mx's for the domain, the message gets accepted no problem. Or am I wrong to deduce from the logs that courier is using the wrong host?

Thanks,
