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.

 

Hello,

There is no way to prevent the spoofing itself due to the nature of Internet email, but you can avoid receiving those bounce messages by ensuring that you do not have catch-all enabled on the mailbox you are receiving these bounce messages to.

Does "catch-all" simply remove the bounce messages? I would not want to miss anything intended for me.

Edit: I did already have catch-all unchecked for the address in question, I see. I have removed catch-all for all addresses on the domain just in case.
 

Hello,

What catch-all does is make any emails sent to your domain that don't have a corresponding email address end up in the mailbox with catch-all enabled on it. For example, if you have a domain named domain.com and someone sends mail to abc123@domain.com when you've never created a mailbox by that name, the catch-all would make that email go into the mailbox it is enabled on.
