I was adding RBL blacklisting to my qmail setup, with rblsmtpd using some blacklists which a couple folks on inet-access suggested. I noticed it logging connections from mx2.freebsd.org as being in SORBS: rblsmtpd: 216.136.204.119 pid 45632: 451 Open Relay See: http://www.dnsbl.sorbs.net/cgi-bin/lookup?IP=216.136.204.119 That web page indicates port 25 is an open relay, failing a test on April 7 2004 01:46:38 GMT, relaying from relays@sorbs.net, to spamtest@sorbs.net. I manually confirmed their test, it appears as if it's a relay. This seems surprising since I know you guys have clue. When I test using some of my own addresses, it says Recipient address rejected: Relay access denied So is mx2.freebsd.or intentionally relaying from/to SORBS? On purpose? To fool it into thinking it's a relay when it's not? Any other ideas? I'd like to use some semi-reputable RBLs but can't afford to block freebsd mail. Thanks.
