On this network, I have an Exchange Server (using domain mail.example.com). I had a problem sending an email to a local address : adress@example.com : relay=none, delay=0.01, delays=0.01/0/0/0, dsn=4.3.5, status=deferred (Host or domain name not found. Name service delivery temporarily suspended: host or domain name not found. name service error for name error for name=example.com type=AAAA: Host found but no data record of requested type) I solved this problem using relay_domain in my postfix main.cf : relay_domains = example.com transport_maps = hash:/etc/postfix/transport And in my /etc/postfix/transport : example.com smtp:[mail.example.com] Now I can send mails on @example.com, and I have tested some majors webmails (Gmail, Yahoo, Hotmail...). It works. But why I got this error on my adresses "@example.com" ? How can I be sure I never find this error on another domain ?

Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top Postfix error: Host or domain name not found up vote 1 down vote favorite I am http://serverfault.com/questions/577134/postfix-host-or-domain-not-found using Raspbian and the Postfix (version 2.9.6) service seems to be automatically run when I boot, but if I want to send a mail, the email stays in the queue: $ mailq 26CB72201F 443 Sat Sep 19 19:44:17 user@mail.example.com (Host or domain name not found. Name service error for name=smtp.gmail.com type=A: Host not found, try again) someone@gmail.com If I restart the service (sudo service postfix restart) then emails work until the next boot. Why? What is the difference? During the http://superuser.com/questions/975337/postfix-error-host-or-domain-name-not-found Postfix installation I chose the configuration “Internet with smarthost” but then I followed a tutorial for …Internet Site” to finish the configuration so this might be the problem(?) I just want to send emails. UPDATE: The problem might be that that Postfix is run before the Wi-Fi is connected. email services postfix share|improve this question edited Sep 20 '15 at 19:08 JakeGould 21k56079 asked Sep 19 '15 at 17:56 clemtoy 11617 I wonder, is this server name perhaps resolved when the system starts, but your nameserver isn't reachable then? –Thomas Weinbrenner Sep 19 '15 at 18:11 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote Shorter answer. With a “Host not found, try again.” it could mean that your server is having DNS resolution issues, or Postfix itself is having DNS resolution issues. But that is the core of what has to be cleaned up. As for how to clear it up, your question doesn’t provide enough details on your base OS or setup to give a succinct answer. You seem to be running Ubuntu/Debian if you are running sudo service postfix restart, but what other details can you provide? Longer answer. Possibly connected to resolv.conf mysteriously disappearing. Based on the error: Host or domain name not found. Name service error for name=smtp.gmail.com type=A: Host not found, try again. It seems like you are using Gmail’s SMTP servers
