You are my hero!  Gonna try this out.

I haven't seen this on Cyrus yet, but it happens all the time to me on UW imapd.  It seems to be a bug in OE related to error handling.  UW imapd (using mbox format) gets very confused when OE opens multiple sockets on the same folder, and usually drops one of them.  Sometimes, when that happens, OE thinks the message has been deleted from the server.  It can also happen if you try to read a message after OE has fetched the headers but before it's actually fetched the body.

You don't have to delete and recreate the account to work around the problem; simply drag the offending message to another folder and back, then purge deleted messages in both folders.
