My email address was disabled by my ex-employer, which was then accessed (possibly by changing the password?) and my details were then tampered with. Example: I had about 5 domain names in a Namecheap account, the ex-employer then did the 'forgot password'. It happened for a few other services. But the worst was seeing parts of my medical files leaked on some IRC server.
Now I'm not quite sure what to do in regards to email. The whole ordeal made me quite sick in the stomach. I have my (new email) settings set so that all emails are deleted after request (on the server) - it's probably a crap way but I didn't know any other option. So I'd expect anything that backs up my email to be -hardcore- on security...
It did make me realise how much malicious damage that can be done if someone gets access to your email, and the importance of keeping work / personal emails separate. :-(
