Hmm. I see what you mean there. Yeah, it could be worthwhile to add a switch 
that allows to toggle between strict and less strict handling on RBL hits.

Of course: The RBLs are optional and the default sendmail.mc (and *.cf) 
doesn't use any. So unless you manually add blacklists through the GUI this 
ain't a problem.

Personally I'm not really a friend of using RBLs directly in Sendmail and 
where a single hit from one RBL leads to mail rejection. I'd rather use RBLs 
in SpamAssassin where a RBL hit increases the SPAM-score of a message, but (if 
it's just the RBL hit and no other SPAM indicators are found) usually lets the 
message still go through.

I'll put your suggestion on the to-do list, though. That will be useful to 
have.
