There are probably better solutions than this but here are a few ideas:
- Don't allow mail from the outside world to your distribution lists
- Create a mail policy for your distrib lists that drops spam instead of quarantining it
- Only quarantine suspect spam and drop spam positive (I have yet to see a false-positive that was above suspect spam). Doing this most folks get 1-2 notifications a week instead of 7.

hi
Thanks for your replay.
-you right about now allowing to send from outside world to DL ,i tried it by allowing only authenticated users to send to DL in my exchange server .
but since allot of mail from inside domain are not actually authenticated by AD .
i dropped it .
I will try you second suggestion even though i a bit worried by dropping the spam instead of quarantine it .
Thanks

Hi
im talking about email enabled DL .
The solutotion i see is to use ldap query for objectclass=group (AD2003).
Enable it on the specific listner.
the you need to add a incomming mail policy ,where the query search for the string "group" ,if true drop the mail don't quarantine it -then it will prevent the notification .
that it -what i could done in BrightMail in one click .
