Is it possible to create "rules" when an email arrives in the maildir inbox, to forward with a specific subject etc. Similar to the rules you can create in Microsoft Outlook when an email arrives.

On certain of my emails, I neeed to forward it if it meets certain criteria/s, and then fordward it to my SMS getway/s etc.

Please advise.



You can indeed do that, though that's something you would do as the user from within Usermin.

To access Usermin, you can either login as the user at https://domain.tld:20000, or from Virtualmin, you can click Edit Mail and FTP Users, click the username, then click the "Log into Usermin" button at the bottom.

Once you're in Usermin, click Email Filters -> Add new filter.

You can use that screen in order to add a variety of mail filters.
