Exchange 2010 - How to limit message size when sending to more than one/few person

Hi,


I want to limit message size when sending to more than one or a few person on my domain.

I checked the Receiving  limit configuration for a specific people or specific distribution group.

In case of someone who send email to a few mailboxes inside my domain that are not listed in the specific rule, So there is the problem.

although  - When expanding the distribution group from "TO" in outlook(show the members), Should the rule break because the distribution group name has been removed?


Sorry for my lame English(working on improvement).

Best Regards,

Eliran
