if you can't use existing rbls ..
- you can create your own local rbl of spam you did receive
instead of assuming that those that are in the various rbls
are in fact accurate which is not always the case
- other option for sendmail is to use:
- bayessian filter
- both of which is more than a minute of work like the rbl entries

yup.. but even those can be tricky ...
MX records are not required to send/receive emails
sending hosts does NOT need to have reverse DNS to work
"work" means that the non-techie sitting in front of windoze-XP
and can send/recevie emails and giga-byte-attachments w/o any
"work correctly" for techies can be flame bait ..
and as with all flame bait, is usually not worth the time on
either party other than a good blood pressure and patience test

not all users have the ability to "properly configure" tehir sending mail
servers or that the admin knows what to change or where .. or how ..
spammers are not dumb ... they know exactly what to do to get around
any/all spam filters... they're always 1-step ahead of us ..
- worst case are soem of the hotels, that send mail out
as localhost to get around the CEOs (in)ability to send
outgoing mail on their laptop thru their corp servers
in which, the corp email servers, should reject hotel guests
from relaying emails from hotels thru the corp mail server
vpn would be better, but than, if the ceo can vpn from
the hotel room, so can the spammer ..
endless problems.. good for job security ..
