How do I block emails that are addressed to main recipient name?

Resending request replacing @ with (at) in order not to trigger personal info block of request:

For example true recipient is xyz(at)gmail.com.

Spammed email xyz.abcde(at)gmail.com.

Also receiving email sent to xyz(at)aol.com or xyzzy.abcde(at)aol.com even though I do not have an aol account.

Please help on to handle this as spam is driving me crazy.

Thank you in advance

Spam is a fact of life. Apple uses the term Junk in there Mail software, make changes:

Mail.app>Preferences>Junk

Mark it as Junk.

If Junk mail is not working for you as expected—

If junk mail filters aren’t working in Mail on Mac - Apple Support

Change Junk Mail preferences in Mail on Mac - Apple Support

Reduce junk mail in Mail on Mac - Apple Support

Identify and filter junk mail in iCloud - Apple Support

Change Junk Mail Advanced settings in Mail on Mac - Apple Support (IN)

Change Viewing preferences in Mail on Mac - Apple Support (IN)

Mail advanced junk mail settings on Mac - Apple Support

Change Junk Mail Advanced settings in Mail on Mac - Apple Support (IN)

Not to overwheln you but there is both server side filters and client side (on your Mac) filters

You maybe able through a browser log into your mail account and make some change there—for more aggressive or specific spam filtering...

—if no insight or resolve

If Junk mail is not working for you as expected you can turn it off in Mail>Preferences.

You have the option of installing a third party spam filter. ex.
