Global Spam Filter: Reject All Email that isn't from .com or .net or .org or other .TLD

You know how there is like 100s and 100s of domain endings? The .loan, .ninja, .guru, etc..? How do I reject all email that isn't from a traditional .com, .net, .org, etc.. domain?

Do I really need to create additional rule filter and manually add all domain extensions?Here is an example rule I use:



It would be a bloody nightmare if I had to create 100s of rules just for those second level (hipster) domains. SpamAssassin doesn't always work and I get emails that tell me buy a product to regrow my hair.

 

Thanks for suggestion, it is most helpful.

Might you know @cPanelMichael, if a single rule would properly work if using a comma (or even wildcard *) to separate top level domains? Do you recommend wildcard and comma? So a rule might look like either:



Thanks
