I just upgraded a home system from 2.2.12 to 2.3.3 and started getting the "invalid mailbox format" error. I then ran reconstruct and it worked after that.
Before the reconstruct, if I downgraded back to 2.2.12, things would get back to normal. I remember seeing a similar problem someone had with an upgrade to 2.3.x in this list but I can't find it in the archives (or I'm mistaken). ---- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
