Account Expiration

Your email is tied directly to your RCS account, so it will become unavailable when your RCS account does.

Your linux account will not automatically expire as long as you continue to change your password before it expires. Currently you must change your password at least once every two years, and will be warned when you log in starting 30 days before it expires.

Please see http://alumni.rpi.edu/s/1225/index.aspx?sid=1225&gid=1&pgid=722 for details on RPI's "email for life" program that lets you have a fixed email address that gets redirected to an email address of your choice for free, or you can pay for space to host it.
