Hi,
Maybe the following additional information can help in debugging...
The error messages were:
> Oct 18 07:35:58 dovecot: IMAP(user): UIDs broken with partial sync in mbox
file /var/mail/user
> Oct 18 07:35:58 dovecot: IMAP(user): mbox sync: UID inserted in the middle
of mailbox /var/mail/user (15314 > 9604, seq=5, idx_msgs=224)
> Oct 18 07:35:59 dovecot: IMAP(user): file mbox-sync-rewrite.c: line 405
(mbox_sync_read_and_move): assertion failed: (need_space ==
(uoff_t)-mails[idx].space)
> Oct 18 07:37:42 dovecot: IMAP(user): mbox sync: UID inserted in the middle
of mailbox /var/mail/user (15314 > 9604, seq=5, idx_msgs=224)
- We just switched from UW-IMAP to Dovecot, so the mailbox has been
created by UW-IMAP.
- It doesn't help if I delete the dovecot indexes and kill the user's
dovecot process.
- It doesn't help if I copy all the mails singularly from the old folder
to a new folder (with mutt).
- It helps to move the folder away and start with an empty folder.
Maybe it has something to do with the X-UID headers by UW-IMAP?
I noticed that the folder contains mails with duplicate X-UID headers.
Attached is the output of 'grep X-UID /var/mail/user'.
Next time that this happens, I will try to grep out all the X-UID
headers from the mailbox.
Cheers
David
