Strange Mail Stuck In Mail Queue...

[JnascECSI]

I keep seeing these in the Mail queue and it had me stumped until today after looking up the UID which seems to be qscand. What would be causing emails trying to be sent to this address administrator@192.168.1.2 ?

Well, if the "from" or "reply=to" line in the header of an incoming email is administrator@192.(etc), and it is being sent to a non-existent account which is set to bounce rather than reject, then you'd end up with an email like that in your outgoing queue.

This is just one possibility, mind you. I'm sure there are other possibly causes.

Take a look in your /usr/local/psa/var/log/maillog to see where these emails are coming from and who they are addressed to. If you can't find anything in the log, my theory is out of the window.
