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.
