In Exchange 2010 we can moderate mails sent to a distribution list, directly from the distribution list parameters. It is the same moderators for all the senders.
This is perfect except that wen cannot choose different moderators for different senders.
There is a second option, with Transport Rules, but it cannot moderate mails sent to distribution groups. This allows to moderate somes users by some moderators and other users by other moderators but can only moderate mails sent to, for instance, external recipients, or some recipients but not to a distribution group. This is sad because this option is very good because it allows to "forward the message to the sender's manager for moderation".
So, here is my question, how could I manage to set moderation for a distribution group but moderators are respective managers of the senders?
Do I really have to set a huge transport rule saying: if mails are sent to each of the 300 employees then send the mail to the manager for moderation? This is nearly impossible, if it doesn't crash while adding the 300 users.
Thank you in advance for your help
