Based on some evidence in the mail logs of my personal server, it
* I still have an account on tiddlyspace
* That account can still receive mail and is forwarding to my
cdent @ peermore.com
* Spammers are sending email to cdent @ that host, I initially thought
perhaps using it as an open mail relay
Please at least kill my account and change the contents of
/etc/aliases to not have any references to cdent.
 The email indicated that I had an alias, so I checked to see if
I could still ssh in. I could. This surprised me. I looked in
/etc/aliases to see if there was any me in there and there was.
 I tried to look in the mail logs in /var/log and they indicated
that the exim config is broken however a web based diagnostic tool
indicates that tiddlyspace.com is not an open relay, just that
people send spam to users with accounts on it. If I stop having that
account that aspect of the problem will go away.
