There's a way to do this in your sendmail configuration (assuming you
are running sendmail):
O MaxRecipientsPerMessage=n (where n is the max number of recipients)
I am sure a good google search will explain more on this setting.
If you are not running sendmail, this will be of no use to you.
The advantage/disadvantage of this is that it runs before MailScanner
is involved. This is an advantage in that the message is quickly
rejected (and the sender notified) before MailScanner has to process
it. It is a disadvantage in that it won't be seen by MailScanner and
therefore not quarantined for analysis.
My 2 cents worth...
