How to remove a invalid address in OTRS 5

Hi!

Using OTRS 5.0.25 on Linux with MySQL.

In our ticket system, we would like our team to respond tickets for company e-mails only.
The team has been warned to remove invalid adresses, but nevertheless, I also would like to add a rule for OTRS to automatically remove any address @gmail.com, @hotmail.com, @outlook.com (the most obvious).
