Same thing
I had the same thing happen. 3 IMAP accounts disappeared. I re-confied one of them, but when I used it it would mix & match email headers and email bodies from different accounts when I viewed and sent emails. I went into Manage Applications and cleared all data from the email app, and then re-configed everything. This seems to have helped with the mix & match problem. I hope the accounts don't get deleted again.
One theory I had, was I had put the phone in my pocket after checking email without putting it into sleep first. When the touchscreen is rattling around in your pocket alot of things can happen....droid even managed to send me an email on its own! Don't know if this theory holds up for everyone else, but I'm just putting it out there.
