Guys, I'm stuffed. I had Postfix running on the server for months. But all over sudden it stopped sending emails to extarnal domains. I must fix it, but I run out of ideas. PLEASE, HELP! Here is my sad story. Emails are Ok on the way from client app to my server. They are actually being stuck in the queue as deffered. So, I have checked logs: Code: Aug 6 22:01:50 www postfix/smtp[3592]: 4F0272264CF3: to=, relay=none, delay=386320, delays=386264/0.06/56/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=mamail.com type=MX: Host not found, try again) "Host not found, try again" looks like it is a DNS issue. O'Reilly postfix definitive guide says: "The DNS query produced no answer. Either the DNS server is not reachable, or it is broken." It seems to be reasonable. So I have checked /etc/resolv.conf : Code: www:/etc# cat /etc/resolv.conf domain croup.de nameserver 208.84.145.233 nameserver 208.84.145.155 nameserver 208.77.96.36 Then I checked whether rimary DNS server is working: www:/etc# man nslookup Reformatting nslookup(1), please wait... www:/etc# nslookup > server 208.84.145.233 Default server: 208.84.145.233 Address: 208.84.145.233#53 > set q=mx > googlemail.com Server: 208.84.145.233 Address: 208.84.145.233#53 Non-authoritative answer: googlemail.com mail exchanger = 10 alt2.gmail-smtp-in.l.google.com. googlemail.com mail exchanger = 50 gsmtp147.google
have problem with my server. In Mail Queue I get this: Code: -Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient------- 7B1221F43B0 3547

Try to do a host gmail.com; see if you get results. –laebshade Sep 25 '11 at 23:46 host gmail.com gives gmail.com has address 74.125.233.24 on the line, and then ;; connection timed out; no servers could be reached on the second. But it's strange because I can ping it. –Tshepang Sep 26 '11 at 0:23 2 How about host -t mx gmail.com ? You're right, though, this is somewhat odd. –Shadur Oct 20 '11 at 13:15 1 Another thought: can you add your /etc/resolv.conf to the question? –Shadur Oct 20 '11 at 13:21 1 Yeah. Signs point to a dodgy resolv.conf, possibly due to network-manager or resolvconf not quite playing ball. –Shadur Oct 22 '11 at 7:32 | show 3 more comments 5 Answers 5 active oldest votes up vote 4 d
and /etc/resolv.conf differ you should copy /etc/resolv.conf to /var/spool/postfix/etc/ . The error comes because you run postfix as chroot and postfix can then only see files in /var/spool/postfix/ . During install postfix takes a copy of /etc/resolv.conf and place it in its own directory. There could be more errors than that. Check /var/log/mail/warnings and /var/log/mail/errors and make sure you have verified all files. In case of more trouble run the command postfix check. You could also get error messages like: postfix/postfix-script: warning: /var/spool/postfix/etc/localtime and /etc/localtime differ postfix/postfix-script: warning: /var/spool/postfix/etc/services and /etc/services differ Which implies that /etc/localtime and /etc/services should be copied. Before doing anything check what the difference of the files is.
