About
Postfix is an open-source Mail Transfer Agent for POSIX systems. It is fully supported by Webmin and is part of the Dovecot stack.
Notes
aliases
To set up aliases, either edit the file specified by the alias_maps setting in main.cf (/etc/aliases by default) and then run newaliases (or "postalias /etc/aliases") to update the database, or else use Webmin ("Mail Aliases" icon, then click on the "Create a new alias" link).
Notes:
- Webmin seems to automatically run newaliases when you add or modify an individual alias, but not when you use it to edit the /etc/aliases file directly. Changes made to /etc/aliases will not take effect until the database is updated.
- Stopping and starting the postfix daemon does not update from the aliases file; you still have to run newaliases.
catch-all
To set up a catch-all address, edit main.cf and set the following parameters:
- local_recipient_maps =
- luser_relay = whereToSend
The syntax for whereToSend is explained here.
Examples:
- luser_relay = $user@anotherdomain.org
- forwards all email addressed to "invaliduser@firstdomain.org" to "invaliduser@anotherdomain.org"
- luser_relay = youraddress@anotherdomain.org
- forwards all email addressed to invalid users to "youraddress@anotherdomain.org".
