I've reviewed the pcap file, looking for "ip.addr == 173.194.65.27" for all times between 12:31:39 (when postfix received the message), and 12:48:22 (when it was successfully delivered), and there are no frames that mention 'acrespo' at all (except the initial reception, and the final delivery). There was no deferral attempt.
The only filter on the original dump was "not port 22". --Jason On Fri, May 31, 2013 at 5:00 PM, Wietse Venema <wie...@porcupine.org> wrote: > Jason Price: > > > *May 30 12:38:23 rmail3b01 postfix/error[6485]: DD01F7B0: > > > to=<acre...@aaaaaa.com>, relay=none, delay=403, delays=0.01/403/0/0, > > > dsn=4.4.2, status=deferred (delivery temporarily suspended: > conversation > > > > However, while watching tcpdump output very carefully, I can find no > > evidence that postfix ever attempted to send this message at or around > > 12:38 on May 30th. > > Postfix does not deliver mail when it says "delivery temporarily > suspended". > > Wietse >
