Transport Rule - Don't send back to sender

Posted on 2011-03-23
Last Modified: 2012-05-11
When a user is sending to a distribution group in which they are part of. How do I stop the email from sending it back to the sender? I'm aware that you can set a rule within outlook or use the expanding tree feature. But what I'm trying to do is; setup a transport rule in EMC. Any ideas or past experiences?

You cannot use a transport rule for this, or at least if you can I have not found one.

The reason the sender gets the message as well is because the group is a Mail Enabled Security group and not a Distribution Group.

Thank demazter. I'm a bit confused. Mail Enabled Security Group and Distribution Group? Are u saying Distribution Group is a mail enabled security therefore it will not work. Please clarify. Thanks.

When you create a new distribution group in Exchange 2007/2010 you have the option to create a security group or distribution group.  If you do this through the Exchange Console they will be mail enabled.

The difference being that a security group as far as Exchange is concerned will send the sender the message if they are part of the security group.  It shouldn't do this if the group is a distribution group.

You don't need to, if it's a distribution group they won't receive their own message (or they shouldn't)
