Exchange Missing E-Mails

silvesj
Hey Team,

We recently implemented the Sophos UTM e-mail filtering. Everything seemed to be flowing good, until some users noticed they weren't receiving e-mail. Doing some digging Sophos says the e-mails are being delivered. However; users aren't receiving them? I then noticed when I signed up for a My Sophos account it was never delivered. It's not in my Junk Mail folder either. Any thoughts>

I was able to send/receive a test e-mail to my personal account. See attached screen shot for e-mail I never received.

    Nothing in the Exchange logs at all?  Looking in mailboxes is not good enough, you must look in the logs to see what it happening.  If there's nothing at all in the logs then Exchange services may not be running.  Check the SMTP log on the UTM, it will give you information about the delivery transaction.  Did the UTM replace something else that had the same IP, if so, did you clear the ARP tables in switches between the UTM and Exchange?

    Sorry, a lot of stuff is coming through except for from a few specific domains. Sophos IS passing them on to the Exchange server. However; there's nothing in the Exchange logs saying there was an error or anything like that . 

    I have posted in an Exchange forum as well [:)]

    The Sophos did not replace any other network device.
