I—like a lot of you—was getting lots of “buy this hot stock” spam. The latest change I made to my Postfix installation is to add a check against the Spamhaus Bloclk List. The addition to main.cf is under smtpd_client_restrictions, which now looks like this:
smtpd_client_restrictions =
check_client_access hash:/etc/postfix/accessi
reject_rbl_client sbl-xbl.spamhaus.org
