The email account that is the object of all the email admin I’m looking at is getting hammered with spam.
It’s an old email account, the email address has been around the internet for a decade or so and it has been very public, so it’s not a big surprise that it’s getting spammed.
Over 99% of the spam comes from spoof email addresses (from hacked MailServers, I’m guessing) that begin ‘canada.medic@’.
I set a management rule in MailServer to discard any incoming traffic from all email addresses originating from ‘canada.medic’ attached to any domain name.
That did the trick.
The incoming traffic showed up on MailServer as incoming mail, but nothing was delivered to the incoming mailbox/email account.
