postfix cannot getting my domain name?
- by Kossel
Hi I'm trying to setup webmin+postfix+dovecot+roundcube, for this moment I want things be as simple as possible so I'm using linux users as email accounts.
I can send/receive from the same domain, I mean user1@mydomain.com can send/receive to/from user2@mydomain.com
I tested smtp/imap with outlook and says no problem.
if I send a mail from gmail it reject with error of:
Technical details of temporary failure:
The recipient server did not accept our requests to connect.
when I login with roundcube the email address display in the right corner is something like user1@com and
I get this error message from logs:
[11-Nov-2012 07:39:03 +0400]: IMAP Error: Login failed for user1 from 187.150.xx.xx. Could not connect to com:143: php_network_getaddresses: getaddrinfo failed: Name or service not known in /var/www/webmail/program/include/rcube_imap.php on line 191 (POST /webmail/?_task=login&_action=login)
it says Could not connect to com:143
looks like it cannot read the domain name.
I used http://mxtoolbox.com/ to check the mx record and it says it can find the server of mail.mydomain.com.
I quit sure the problema is from postfix or my server configs, but I have been looking for every config file and cannot find the answer of this. any suggestion I will appreciate.
here are some of my configs (I don't want to make this question too long, I can provide any other information to solve this question):
