Ha!  I only wish my sin-enticement skills were that good.  I'd be at home
with my harem right now.

Seriously, I wasn't trying to start a religious war here.  Just pointing
out the obvious: that the use of spam filters is increasing, that those
filters send as little information back to the spammer as possible, and
that sysadmins can and will take steps to keep their user lists private.

Would it be nice if everyone provided accurate whois, vrfy and ident
services, and gave the sender of each refused smtp transaction a detailed
summary of why the decision was made to refuse it, so that the sender
could correct the problem and try again?  Yup.  But be realistic--it ain't
gonna happen.

Mike
