[Dovecot] new mails don't always show

[Simon Bowden]

Hi,

I was seeing this sort of problem when the indexes were corrupted, 
possibly due to unsuitable locking methods on it (recently changed to 
dotlock, since it's over nfs).

The workaround was to just delete the indexes so they'd be recreated.
The symptom was that there would be strange "UID inserted in middle of 
mailbox" type errors in the error log, plus new mails weren't being 
displayed.

Cheers,

  - Simon
