We ran into a serious problem this morning, which caused all our incoming mail to be in bounce status and not delivered, due this error message:
"status=bounced (host 192.168.2.4[192.168.2.4] said: 550 5.1.0 <SRS0=7H+Q=RG=gmail.com=personjacob@ourcompany.com>: Sender address rejected: User unknown in virtual mailbox table"
The mail was dropped into PMG, ran through spam and virus checks, and after everything was found to be OK, the [pmg postfix/qmgr] service for some reason changed the domain of the incoming mail:
Original incoming mail address: personjacob@gmail.com
Mail address changed by pmg postfix/qmgr: personjacob@ourcompany.com
As a result of this change, PMG no longer forwarded the mail to our mail server with the original address, but with the changed one, which threw away the fact that there is no such mailbox on our own mail server (which is true)
I know this is part of the SRS service... I just don't understand why without touching it, why did it go bad overnight?
