Hi all,
I'm quite frequently receiving permanent delivery failures when sending mail to a particular remote host even though apparently they're responding with a temporary 45x error. The log entry shows a missing code:
2007-11-26 09:55:26.771462500 delivery 252542: failure: 1.2.3.4_failed_after_I_sent_the_message./Remote_host_said:_Read_timed_out/
Now I'm assuming they're at fault here but I need to prove this easily and I'm not sure how to do so without intercepting and logging the smtp sessions (which will take a while as it only happens a few times a day).
Any ideas?
Thanks.
Matt.
