How to Block Dangerous Email Attachments with Regex?
I would like to know that , how can i block email attachment via ASA Regex using ASDM 6.2.
I am able to block websites and stuff like that. But i want to block email attachments which are harmful. As an example i would like to block .mp3 extensions, so that if some one want to send an attachment with mp3 it would get deleted automatically. I hope you got my point.
