Someone has gotten hold of one of my Servergrid-hosted e-mail addresses and has begun using it heavily for spoofing attempts -- sending spam to others using my address as the "From:" address. The result has been a deluge not of spam (though that had started recently as well), but of messages from other servers' spamblockers.
Is there any way through Servergrid's filter to address this, short of changing the e-mail address (an expensive option, given stationery, etc.)? Blacklisting through the webmail program only takes out the servers responding to the spam, and they seem to be endless in number.
