Tim,
I went to register for the bugzilla and found that the confirmation request from 74.84.118.181 was rejected by postfix because 74.84.118.181 does not provide a proper reverse lookup causing:
smtpd_client_restrictions = reject_rbl_client sbl.spamhaus.org, reject_unknown_client
It is 'reject_unknown_client' causing the rejection. From: http://www.postfix.org/postconf.5.html the rejection is caused when:
- the client IP address->name mapping fails, 2) the name->address mapping
fails, or 3) the name->address mapping does not match the client IP address.
I'm no postfix expert, but to let the confirmation through, I just removed 'reject_unknown_client'. If there have been people who don't get the confirmation emails, this may one reason why :)
The actual postfix rejection was:
Feb 28 16:22:21 nirvana postfix/smtpd[6858]: warning: 74.84.118.181: address not listed for hostname pearsoncomputing.net Feb 28 16:22:21 nirvana postfix/smtpd[6858]: connect from unknown[74.84.118.181] Feb 28 16:22:22 nirvana postfix/smtpd[6858]: NOQUEUE: reject: RCPT from unknown[74.84.118.181]: 450 4.7.1 Client host rejected: cannot find your hostname, [74.84.118.181]; from=bugs@pearsoncomputing.net to=<snip> proto=ESMTP helo=<vali.starlink.edu> Feb 28 16:22:22 nirvana postfix/smtpd[6858]: disconnect from unknown[74.84.118.181]
Somebody smart with postfix and bind can probably tell you what the exact issue is. Just looking, I see a helo from vali.starlink.edu and the "warning: 74.84.118.181: address not listed for hostname pearsoncomputing.net"
Hi David,
How exactly did you get this error? My reverse DNS checks out OK and I don't see any problems with a test registration on the Bugzilla.
Thanks!
Tim
