Hmm, as I said, I've used this same version for years on OS X 10.6 without issues, and months together with kmail. I guess I should disable my local account in kmail and run another client (sylpheed :)) to see if that also gives issues or if the KDE PIM imap agent is the culprit.
Truth is that I don't get incoming mail other than cron output in my local inbox, so it's not like it's an end of the world issue ;)

No, the first 64 or so bytes get replaced with garbage, as if there's a buffer overflow when rewriting the imap folder header.

Last time I tried to run something other than UW imapd I couldn't get it set up. Also, I patched the UW imapd to support per-user configuration files that specify the location of the mail folders tree, rather than offloading that to the client (which may not have an imap prefix path feature).
