Spamcop has decided to go off blacklisting all yahoo/shaw etc servers worldwide. I'm seeing about 40 spams per month from Yahoo's *.bullet.mail.sp2.yahoo.com; they're almost certainly the single largest source of spammy email I get. > Example Solution Postfix: > remove: reject_rbl_client bl.spamcop.net > from your smtpd_recipient_restrictions line until they fix their abuse issues. I probably wouldn't use any RBL for pass/fail blocking-- aside from postmaster.rfc-ignorant.org, maybe, and even that one likely needs some whitelisting if your mail system has a non-trivial # of users-- instead, consider using RBLs for scoring.
