Topic: Dependent relay server

==== Required information ====
- iRedMail version: 0.8.4
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): LDAP
- Linux/BSD distribution name and version: Debian
- Related log if you're reporting an issue:

A domain need to send their mail by using their ISP SMTP server which is "relais.videotron.ca". When trying to communicate with user within their own domain, the mail got refused. By searching in the forum I found that we need to setup a dependent relay setting in main.cf (http://www.postfix.org/postconf.5.html# … yhost_maps) but I don't know how to proceed.

Anyone can help me how to setup this ? I need a entire domain (let say domain.com) to be able to use a external SMTP server.

Thank you !
