- You're right - that setting would do it as well. However, that's a Store
level setting enforced on MAPI message submission. As such, it'd need to be
applied to all servers using reg hacks.

Easy enough to create a .reg file to do that -- or use some other
scripting trickery. :-)

- You can set it globally from Global Settings | Message Delivery ->
properties | Defaults tab | Recipient Limits - the default is 5000.

Yeah, but that's a problem. It counts the recipients /after/
distribution group expansion. In a company with one, or more, DL that
might have thousands of members (or other nested DLs that lead to very
large numbers of recipients) you have to set this value to a really
big number. By doing that you allow people to select way too many
individual recipients from the GAL.

However, neither of the above methods can be used to set it selectively
based on AD group memberships.

Nope.

Integrating more of these settings (e.g. max recipients, mailbox
sizes/quotas, deleted item retention, et al) with AD using GPOs would be
great - but the Exchange shell in Exchange Server 2007 is quite powerful as
well, and lets you complete such tasks quite easily. For instance, setting
the max recipients of all members of distribution group FINANCE to 100:

get-distributiongroupmember FINANCE | set-mailbox -recipientlimits 100

One drawback: Unlike GPOs, scripts cannot *enforce* settings - the scripts
need to run frequently (using Scheduled Tasks for instance) to emulate that
behavior.
