If you go to the Knowledge Base ( http://support.ipswitch.com ), and search 
for "recipients", you will find it.  It involves a registry change.

The advantage is that it slows them down.

Yes, but if you catch him before he is done (he probably has 100,000's of 
names he wants to test), he will end up with fewer names.  My guess is that 
it would only cut down his time by about 50%, so you're not talking about a 
huge slowdown for the spammer.

That's correct.  Normally, Outlook would send the E-mail once, and let 
IMail know the 50 recipients.  But, if you restrict it to 20 recipients, 
Outlook would have to send the message 3 times (once to the first 20 
people, again to 21-40, and finally 41-50).
