I'm using postfix as my MTA and lately I've been missing a significant fraction from my usual mail
e.g. email from linkedin and spamassassin list. Tracking it down I see they are all getting rejected by abuseat. e.g. Jun 30 14:20:09 egde postfix/25pass/smtpd[21040]: NOQUEUE: reject: RCPT from mail.openbsd.org[199.185.178.25]: 554 5.7.1 Service unavailable; Client host [199.185.178.25] blocked using cbl.abuseat.org; Error: open resolver; https://www.spamhaus.org/returnc/pub/172.68.1.20; from=<owner-libressl+M1127=jeremy=ardley....@openbsd.org> to=<jer...@ardley.org> proto=ESMTP helo=<mail.openbsd.org> I've removed that from my postfix filters, but is there a current best practice set of rbl filters? -- Jeremy
