I was looking at an issue where the user said they did not get a message from a co-worker.
I was looking in the Post office log and noticed the message was transfered to gwia.
gwia sent it to the external smtp server (Cisco IronPort).
the Ironport sent it to gwia. gwia then transfered it to the recipients Post office.
Why didnt it go from the senders Post office to the recipients post office?
Why might it have been routed to the gwia?
