Ability to block any subdomain in the Blacklisted address patterns
I would like to block @.example.com but it is impossible. Spammers use subdomain in order to bypass the filter.

It's absurd that you can't do this!!!! We are being flooded by constantly changing sub-domains especially from .best and .icu. You need to put this back in.

Please make this happen! This should have been a feature available to us years ago. With TLDs like .best and .icu, it would cut down our SPAM dramatically.

We get constantly swamped with Spam from Turkish ISPs with Mails from ".icu" Domain. Most of the Spam is filtered out by RDSN Checks, but sometimes way too much comes through. We NEED this.

Sophos !!! I manage several firewalls and need this feature to be working so I can stop these CRIMINALS from gumming up my clients email, and putting them at risk of infections from a single slip or lapse of judgement. I am ALARMED and IRRITATED by your lack of response to this important security issue.

Is there anyone with a date on this feature release for the UTM & XG Firewall? This would literally reduce the 1,000s of **** email I get daily.
