Wildcard support for antispam's sender blacklist & excepted email addresses
Under "EMAIL PROTECTION > SMTP > ANTISPAM > SPAMFILTER"
you are able to block email senders by adding their domain. You are also able to use wildcards i.e. "*@domain.com".
Same you can do under "EMAIL PROTECTION > SMTP > EXPEPTIONS" to add a sender's email address to except him from specific rules (HELO, Antispam, etc.) buy using the same format and wildcards i.e. "*@domain.com".
Unfortunately I get more and more spam emails from the same domain which uses A TON of subdomains i.e. the following (german) spam site:
The same applies to whitelist pages i.e. brands4friends.de which are noch also sending from "*@nl.brands4friends.de". So I have to add
That is VERY ANNOYING! Unfortunately wildcards are not applying for subdomains.
However in the field "EMAIL PROTECTION > SMTP > ROUTING" you are able to use as much wildcards as you like to i.e. ".domain.", ".domain.com", "domain." or whatever you like to add.
It would be really helpful it this would also apply to the senders blacklist in Antispam as well as to the email addresses in exceptions!

If a spammer knows you are using sophos, all they have to do is change the subdomain to bypass all your user's blacklists.

I agree, with all the snowshoe spam, this would be efficient in blocking all the spam domains. Please implement this.
