We currently use a Sophos Email Appliance that is going EOL in July. I'm trying to see if Sophos Email will fit our needs. Does Sophos Email support rules to block email at the header level? We'd need to be able to block by keywords (string or expression) in the subject, body of the email, etc. In addition to that we'd need to be able to apply those rules to specific users, not globally.
