We were in the middle of a server migration anyway. When the system comes back up we'll be using Gmail to host email service. You will not lose any of your mail and you'll still be able to access it the way you were before but you will have to get a temporary password from me for the first time you log in.
If I'm not already in touch with you about this, please write to me at andy dot origami at gmail dot com and tell me what the best way is to contact you.
