See appendix D in the admin guide regarding regular expressions.

Use http://regex101.com to help build patterns and test matching.

Make sure to use escape characters where necessary, such as:

https:\/\/domain\.com

The only thing unique to FortiMail is that patterns are case insensitive by default.
