Hmm, this is peculiar!
This mailbox has been unchanged on my test server since September. I've been using it to test each new version of Dovecot just after I've compiled it.
When beta1 was released, I opened this mbox with no problems. However, when I upgraded to beta2, I got "file size unexpectedly shrinked in mbox file /export/mail/a/24/vis99003/INBOX (16895967 vs 16899267)".
Reverting to beta1, it also failed with the same error! I've deleted indexes, restored the mbox from a backup made in October (no changes) and I still get the error. It *does* open OK in 1.0-stable.
I've put it through mboxcrypt.pl, deleted the UW-IMAP pseudo-message (which wasn't converted properly by mboxcrypt) and it still fails to open with a similar error, so I've sent it to Timo (gzipped, of course!)
I've e-mailed this to the list minus the attachment as sending unsolicited 1MB attachments is unfriendly! However, if anybody wants to look at it, please let me know.
Best Wishes, Chris
P.S. The past participle of "shrink" is "shrunk" not "shrinked" - it's yet another irregular English verb :)
