How to block a domain with random number digit in cpanel

[batman4ever]

So here is my situation. Lately I have received around 50 spam emails a day with attachment all contain Trojan , virus... If I look at the message header I can see they all came from different countries, different servers, and all look like these: name@####.com  ( for example: [email protected],  [email protected]  all have 4 random number digit then .com)

My question is there a way to block a name@####.com thru mail filter cpanel? The combination of 4 digit number then .com is so wide range.

TIA

My best guess ... ask the host where you receive your emails (Gmail, hotmail etc. etc.)

I know they have support people to help with problems.
