How to stop sub-domains in BADMAIL

[John McCoy, Jr]

Sorry this has probably been asked a thousand times but here it is.

We keep getting spam from zzn.com, but with sub domains, so it's yes.zzn.com
or friend.zzn.com

I know to stop them by putting this in BADMAIL
@friend.zzn.com
@yes.zzn.com

Can I do it this way?
@*.zzn.com

Thanks all
