Hi All, I recently upgraded my debian server from courier 0.61 to 0.63 and am now having strange problems associated with courier's use of DNS. I have always run with BOFHCHECKDNS=1 (the default) without issue. However, after upgrading all domains were rejected in both inbound and outbound smtp mail. Examples: Jan 25 07:58:25 aloha courieresmtp: id=00000000032E4D3E.000000004B5D8509.00000D76,from=<[email protected]>,addr=<[email protected]>: DNS lookup failed. Jan 25 09:20:06 aloha courieresmtp: id=00000000031FC00E.000000004B5DEDBA.000064D0,from=<[email protected]>,addr=<[email protected]>: DNS lookup failed. Jan 24 18:27:41 aloha courieresmtpd: error,relay=::ffff:209.85.210.189,from=<[email protected]>: 417 DNS lookup failure: gmail.com. Try again later Jan 24 18:28:02 aloha courieresmtpd: error,relay=::ffff:209.85.222.148,from=<3wr1dswaaeyclyo2zto-mprtyyp23rzzrwpr2z503....@groups.bounces.google.com>: 417 DNS lookup failure: groups.bounces.google.com. Try again later. Jan 24 18:49:08 aloha courieresmtpd: error,relay=::ffff:64.79.150.121,from=<[email protected]>: 417 DNS lookup failure: netbeans.org. Try again later. DNS is configured and working fine with all other software on the server. E.g.: aloha:/etc/courier# dig +short MX gmail.com 30 alt3.gmail-smtp-in.l.google.com. 40 alt4.gmail-smtp-in.l.google.com. 5 gmail-smtp-in.l.google.com. 10 alt1.gmail-smtp-in.l.google.com. 20 alt2.gmail-smtp-in.l.google.com. aloha:/etc/courier# dig +short A alt3.gmail-smtp-in.l.google.com 209.85.218.11 aloha:/etc/courier# dig +short MX groups.bounces.google.com 5 gmr-smtp-in.l.google.com. 10 alt1.gmr-smtp-in.l.google.com. 10 alt2.gmr-smtp-in.l.google.com. aloha:/etc/courier# dig +short A gmr-smtp-in.l.google.com 209.85.221.205 aloha:/etc/courier# dig +short MX manawiz.com 0 manawiz.com. aloha:/etc/courier# dig +short A manawiz.com 64.34.170.220 aloha:/etc/courier# I reset BOFHCHECKDNS to 0 to work around this issue, and then for the past couple days have been trying to send a message to this list. Other messages I'm sending, or my users are sending, are generally getting to their recipients, but not messages to the courier-users list. They are all getting delayed-delivery responses with DNS failures, e.g.: <[email protected]>: <<< DNS lookup failed. The only way I'm able to send this message is to subscribe my gmail account and send from there. As best I can tell, my courier installation will not send to the courier-users list. How does courier access DNS? Any ideas on how I can resolve this issue? Having BOFHCHECKDNS=0 is letting much more spam through, a big problem, so I really need to change it back. Thanks for any help, Chuck |
