I can be emailed at

Email chain of custody: Email sent to that address is received by the SMTP server of the hosting company I use for (server is located in Washington, D.C.), and then forwarded to the SMTP server of a different company where I have a shell account (server is located in the UK). I handle all email at the command line in a shell account, on a commercial shared hosting server, via SSH (no users are permitted telnet or other unencrypted protocols); my email is backed up nightly to a Debian appliance in my home (in Massachusetts) via rsync with SSL.
