You added a blacklist to your antispam policy to block any e-mails from the spammer.com domain.
However, your users are complaining that they are still receiving spam e-mails from that domain.
You run the utm test-string test and confirm that the blacklist is not working. What is causing this
problem?

A.
The wildcard character * cannot be used for the e-mail pattern match.

B.
The protocol-command smtp value sender: needs to be added under custom-objects.

C.
url-pattern is not supported for antispam.

D.
The pattern needs to be preceded by an @ symbol.
