Exchange Distribution List Message Restrictions

Last Modified: 2012-06-21
We have an Exchange 2003 SP2 organization.  We have an issue with a distribution list that has nested distribution lists.  We set only certain users to be able to send to all of these DL's. (some VIP"s).  The issue is that they are being removed from certain DL's and not others.  Is there any other process in Exchange that could cause this removal besides human intervention or being a member of a protected group in AD. (not sure if that would impact this setting). I have also checked the DL's that were responding with the NDR's

"You do not have permission to send to this recipient.  For assistance, contact your system administrator.
            <smtp.westlake.com #5.7.1>"

The setting I am specifically talking about is the DL's Exchange General tab.  We have it set to

From Authenticated users only - checked

Its not 100% clear what you are referring to.

If it the email not reaching everyone, then the only thing I can think of that would cause email not to be delivered to all recipients is a restriction on the number of recipients.

Nothing else in Exchange could change things. Protected group membership has nothing to do with email group use. Protected group only comes in to play with permissions.

If you are making a change and it is changing back, then that could be caused by replication problems, where the change is being overwritten by settings from another DC.



Ok, sorry if I wasnt clear enough.  I can only point to the AD replication problems as a possible cause.  We have set the restriction on delivery to 25000 so we know it isn't that.  We only have 2000 users.

Thanks for the clarification on the protected groups.  I know that the permission of send as get changed if a user has been granted that right and they are in a protected group.  I just wast sure it the "send to" permission for a DL could have the same issue.  

Thanks again.

If you only have 2000 users I would be looking to have the maximum around that number, otherwise you are exposing the server to abuse.

Replication is about the only thing it can be, but of course that brings lots more problems - ie finding which DC is causing the problem.
