That sounds like Mail.app is creating new custom flags. What does
X-IMAPbase header look like in the first mail?

Anyway, rewriting isn't too well optimized yet. It's a bit better in CVS

(which might be good enough for most), but "optimal" rewriting requires
a bit larger changes.

New mails shouldn't require rewriting, especially the whole file.
