Recipient Limitation query

[Julian Field]

A very quick Google resulted in this from the sendmail documentation:

confMAX_RCPTS_PER_MESSAGE    MaxRecipientsPerMessage    [infinite] If 
set, allow no more than the specified number of recipients in an SMTP 
envelope. Further recipients receive a 452 error code (i.e., they are 
deferred for the next delivery attempt).

Is that close enough to what you need?
