How do I configure the mail server on my appliance?

MangoApps uses PostFix as its MTA.

The configuration files are located in: /etc/postfix/ The file you would want to modify is: /etc/postfix/main.cf

As mail servers can be configured in many different ways, please consult http://www.postfix.org for detailed configuration instructions.

In general, it is sufficient to just change the mail relay server IP to the mail server you would like to relay all the emails from.

Don’t forget to restart postfix for configuration changes to take effect (/etc/init.d/postfix restart).
