Exchange filtering valid email

Posted on 2012-09-05
Last Modified: 2012-09-05
I have a few users who are getting mail filtered.  I see it passing through our Firewall email filter, it passes through our Sophos email appliance and then from the following message it looks like they are being bounced by Exchange 2007 email filtering.  Is there any decent way to read the Exchange log to find out why they are being bounced. I read the log file and can't make heads or tails of what it is saying.  Is there a decent way to read rejected information?

Here is the message that the people are getting who send the messages -

    Check the Domain isnt in an RBL at  your exchange box could be refusing it.

    Also forgot to add

    Step1) Exchange Management Console
    Step2) Server Configuration -> Hub Transport
    Step3) Select Server - Right Click Properties
    Step4) Log Settings
    Step5) Enable Message Tracking Log / Enable Connectivity Log
    Step6) Save, re-send message and then you can look in the path it gives you at the logs and you will get a detailed send/receive log may give you the reason in there.

    If you are using an appliance, why are you using the Exchange filtering as well? Just turn it off. Let the appliance do its thing. The Exchange filtering is pretty basic in all respects, and that includes reporting.

    Which options do you have enabled in the antispam filtering options? The only one I tend to use is recipient filtering, but that should be done by the appliance.

    Benji - good information but I think the best course of action is as Sembee says .  "Just turn it off"

    I have thought of this for a while as the only things Exchange seems to filter is things I want.  I had already created exceptions for half a dozen people to not be filtered in any way.
