I removed that from the issue, the addresses are correct. If the user 
sends a single email everything is fine. The message that is failing has 
over 100 rcpt to addresses. Of course, _one_ email address is incorrect, 
so the entire connection is rejected.

I should have caught that in the logs, it's been a very long week.

Thanks,
