We just release freely a package that allows you block unknow people to create tickets on your system throught the email.
The system also bounces a customizable message to the sender.
It is also possible to move the unwanted message to a specify queue (something like Junk) instead of discarting it.
Please check this documentation for more information.
Obs: Complemento is not responsible for this package usage unless it is installed by our team on your OTRS instance.
