VirtualMin virtual mail server problem

Hi.

We are trying to create mail server on a seperate server for our domain. Currently domain.com is pointed to our webhoster where the website is located. We would like to have the MAIL (only mail) pointed to an OVH VPS Server running webmin/virtualmin/postfix.

We have created an A record pointing mx.domain.com and mail.domain.com to the OVH VPS IP (and also set the MX record of domain.com to point to mx.domain.com).

Have tried to add domain.com, mx.domain.com, and mail.domain.com as virtual server through virtualmin panel - and added a couple of email user accounts, but doesn't seem to work. Always get Relay access denied or 'looping back to myself' - depending on the settings I adjust in postfix's main.cf.

(PS! Pointing the entire domain.com to OVH VPS IP, creating virtual server and then creating mail accounts works just fine!)

Here is the Postfix main.cf:

See /usr/share/postfix/main.cf.dist for a commented, more complete version Debian specific: Specifying a file name will cause the first line of that file to be used as the name. The Debian default is /etc/mailname. myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) biff = no

appending .domain is the MUA's job.

append_dot_mydomain = no

Uncomment the next line to generate "delayed mail" warnings delay_warning_time = 4h

readme_directory = no

TLS parameters

smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for information on enabling SSL in the smtp client.

Any help is appreciated. Thanks!
