Data-loss bug fix (Issue #2839)
-------------------------------

This bug affects upgrades to all Cyrus IMAP 3.0.x releases prior to
3.0.11, where mailboxes have existed from 2.3 and earlier.

Specifically, mailboxes that either:

* still have an index version less than 8, or

* previously had an index version less than 8, but were upgraded to
  a newer index version by Cyrus IMAP 2.4 or 2.5, or

* previously had an index version less than 8, but were upgraded to
  a newer index version by some earlier Cyrus IMAP 2.3.x versions
  (unknown which)

may contain message records with an uninitialised modseq of 0.

Some later versions of 2.3.x (unknown which) would rewrite modseqs of
0 to 1 while upgrading indexes.  If one of these versions was used to
upgrade the index, then there will no longer be message records with a
modseq of 0.

This behaviour was removed during pre-2.4 refactors, so Cyrus IMAP 2.4
and 2.5 do not replace modseq of 0 when upgrading indexes.

A new API introduced in Cyrus IMAP 3.0.0 resulted in index records
with a modseq of 0 being completely ignored (therefore invisible to
users, and apparently “missing”).  This includes the *reconstruct*
utility, which means that attempting to fix the “missing messages” by
running *reconstruct* will ignore (and maybe remove) the existing
index records, and then “rediscover” the message files on disk and add
new records for them (without the index-only data from the old record,
like seen state and other flags).

Cyrus IMAP 3.0.11 no longer ignores these records.

  Moench-Tegeder, Xavier Guimard)
