And I respect your decision to accept that responsibility.  I would also 
do so quite willingly if it was a normal part of a mail server's load, 
or even an option that most MTAs came with by default.  Hm.  Is it?  
Postfix does.  What about the other big ones?  Which ones do/don't?  
Addons and milters don't count.

I'm not sure I'll ever be comfortable using SAV, even if it does turn 
out to exist in most MTAs.  But thanks for your kind permission.  :)
