I have a VPS based on Ubuntu, it has installed whole LAMP, everything needed for a web server and it works perfectly, but I'm still not able to configure it as a mail server....
I have configured MX record for my domain mail.mydomain.com and this part is OK, I also installed Postfix, Dovecot and Roundcube, configured it using this tutorial: http://ubuntuguide.org/wiki/Mail_Server_setup
And after hours of configuring it doesn't work. I have experience with Linux and web hosting, but I successfully configured mail server once in past on Debian 6, and that with help from there.
When I try to send email to me my gmail says:
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain mydomain.com by dc147738a1117e4c12273.mydomain.com. [MY_SERVER_IP].
The error that the other server returned was:
554 5.7.1 <
[email protected]>: Relay access denied
Also I have Webmin control panel which works perfectly, how to configure postfix and dovecot from there?
Thanks in advance.
