Outbound E-mail rate limiting for users

["Kincaid, Chris" <chris_kincaid () REDLANDS EDU>]

Colleagues,

Do any of you limit the amount of outbound e-mails a user can send in a given time?  The reason I ask is we are 
attempting to throttle outbound messages to cut off before we send out 75k spam messages in an afternoon, and then get 
blacklisted.  We use proofpoint, and they have a patch to throttle down outbound users after a threshold is crossed. I 
just don't want to set it too tight and cut off anyone legitimately sending out messages

Thanks,
