Hello,
I'm seeking a workaround for Microsoft's litany of IPs landing on DNSBL.
They'd like all mail irrespective of DNSBL status to be delivered, which
requires a skip if the sender IP is blacklisted in postscreen. With
separation between postscreen and smtpd, postscreen rejects the
connection before handing off to smtpd so smtpd_recipient_restrictions
isn't triggered.
Is there an appropriate workaround that allows postscreen to report
DUNNO after DNSBL checks if the recipient matches in a table?
Sample line:
Mar 15 13:51:22 atlas postfix/postscreen[5978]: NOQUEUE: reject: RCPT
from [1.2.3.4]:51944: 550 5.7.1 Service unavailable; client [1.2.3.4]
blocked using zen.spamhaus.org; from=<x@y>, to=<a@b>, proto=ESMTP,
helo=<aspmx3.googlemail.com>
Postscreen config:
postscreen_dnsbl_action=enforce
postscreen_dnsbl_sites=bl.spamcop.net*2 b.barracudacentral.org*2
zen.spamhaus.org=127.0.[0;1;2].[0..254]*2 list.dnswl.org*-2
