Maximum Delivery Restrictions

Greetings!

I am trying to prevent several users (couple hundred) from sending mail to more than ten people (because of DL abuse). I know I can do this via SMTP VS, account, and local the local user's registry.

All of which won't work since SMTP is all of noting, each account is too time consuming, local registry is too hard to coordiante and implement.

I have delivery restrictions setup on the DLs, but users simply click the plus in Outlook to get around it.
Is there another way?

Hi jjdurrant,

You can set a limit on the number of recipients an email can have.

This would have to be done on each user's local computer right?

Hi jjdurrant,

You only have to do this on the Exchage server. This will affect everyone.

I'm not sure where in the local registry you could make this change.  However, if there is a local registry setting you know about, it's very possible that this could be controlled using group policies.  You would need to install the Outlook group policy snap-in (.ADM) file, which is part of the Office resource kit.  You can download the Office resource kit (assuming you're using Outlook 2003) at:

I'd rather not involve Outlook. :)

Hi

You can hide the members of the distribution list in AD. That way they cannot expand it.
