[SWLUG] QMail recipient check

[Foeh Mannay]

Hello, all.

For the sake of anyone else who wants to do the same as me... I found a 
patch that does exactly what I want and nothing more called "badrcptto" 
at http://patch.be/qmail/ - installed and tested fine. Created a file in 
/var/qmail/control called badrcptto and dumped a one-liner in there with 
the address I want to reject and it cheerfully refuses mail for that 
recipient in the SMTP conversation, rather than trying to send a bounce 
after the fact :o)
