It's stories like these that reinforce my own justification for running my own email server.
I would recommend you run your own email server - it's both fun (you get to set it up yourself, add any features you want), and rewarding (you don't have to worry about the "rug being swept from under your feet"). The only caveat is time - time for SMTP servers around the world to know that your mail server's IP is not sending spam - and filling out some forms to unblock the server's IP address.
Since moving in 2014, I have had no hassles at all, and I continue to tweak things to my liking.
