Restrict email in the server

Hi!Is there any way to create rules to prevent users from sending emails that matches certain criteria?

For example one criteria would be to reject emails (non-delivery failure) if the size is over 3 MB and at the same there are more then 2 external internet recipients…

or another criteria would be to reject emails having more than 100 recipients (including expanded groups).

This has to be a server solution, I don’t like modifying templates.

Thanks

Look in the Server configuration document(s): Router/SMTP \Restrictions and Controls.

I think pretty much everything you want is on these tabs.

But, restricting to more than 100 users…hmmm. Not aware of any server config setting for that one. You could do it, but as you said, it would mean design chnages.
