Try some blacklists with sendmail.

you will smile with glee seeing each connection blocked. oh yea do research into each one. i dont use them all atm.
also check spamassassin, razor2, dcc. procmail too. or maildrop. amavisd and the uvscan binary.
i wish i could explain more, but understand how to set up all that crap and you could sell spam/virus solutions.

Hello all.
I start using blacklists also with sendmail. The spam reduced A LOT . I just wanted to ask where exactly do I have to put the rule in the configuration file. Since I put the rule when my users send email their mail client takes too long to send the email. If I take out the rules the mail is sent immediately (testes with outlook, eudora).
Thanks in advance.
JB
