My Dovecot 2.2.16 server is interacting poorly with a variety of mail
clients. The symptoms include disappearing messages, mismatched summaries,
duplicated messages, and excessive full re-downloads.
Dovecot 2.2.16 on FreeBSD 10.1-release r280247M ZFS is interacting
suboptimally with various email clients. Output of "dovecot -n" further
down.
ZFS does have some features, that allow backups and restore and such, if I
remember correctly.
dovecot.log shows runs of this error:
Apr 15 09:02:37 imap([email protected]): Warning: Maildir
/mail/domain.com/user//.Sent: Expunged message reappeared, giving a new UID
(old uid=306286, file=1429102024.M826331P1156.host,S=1678,W=1724:2,S)
Such message I saw only, when I manually changed files in the Maildir
directory. That's why I pointed out ZFS above. Do you use some strategies,
that freezes a Maildir, then do something (e.g. backup), then thaw the
Maildir. During the backup, a client could delete a message, which reapper
after thaw.
Other possibilities: rsync/copy, vi, ... on file system level
When you operate on filesystem level on the Maildirs keep in mind, that
filenames store message flags and status, which may change regularily.
I've set
mbox_dirty_syncs = no
mbox_lazy_writes = no
you are using Maildir, no? They don't effect Maildir.
mail_location = maildir:~:CONTROL=/var/no-quota/%u
this one hits me:

"Home directory shouldn't be the same as mail directory. It's possible to
do that, but you might run into trouble with it sooner or later. Some
problems with this are: " ...
mail_plugins = quota mail_log notify fts fts_lucene
I don't run FTS, where does lucene store its files? In the user's home?
