i have several domains on my mail server, and it seems somewhere along 
the way sendmail decided to stop allowing the sending of mail by users 
that dont (in its opinion) exist.

problem is, sendmail doesnt seem to think a user exists if his domain 
(as given in the MAIL FROM: line) is anything but sendmail's own 
hostname. so, how do i disable this check?
