Hi,
I’m running Dovecot 2.2.19 with Maildir as storage and LDA for delivery.
I noticed that if I set mailbox_list_index=yes and
maildir_very_dirty_syncs=yes when I login via IMAP the STATUS command
don’t “see” new messages in sub-folders (like Spam).
Example, a new message as arrived in Spam folder (I can see in
Maildir/new/) but IMAP STATUS don’t see it:
. STATUS Spam (MESSAGES UNSEEN)
* STATUS Spam (MESSAGES 139 UNSEEN 0)
(in this case the date of “dovecot.list.index” files is not updated)
If I comment out mailbox_list_index=yes or maildir_very_dirty_syncs=yes
I can see the new message:
. STATUS Spam (MESSAGES UNSEEN)
* STATUS Spam (MESSAGES 140 UNSEEN 1)
(in this case the date of “dovecot.list.index” files is updated after
the STATUS command)
Instead the SELECT command works fine always.
An importante note, my dovecot LDA configuration (on MX servers) don’t
update index files:
protocol lda {
mail_location = maildir:~/Maildir:INDEX=MEMORY
mail_plugins = quota acl expire fts fts_solr zlib sieve
}
These because I need to filter incoming email via Sieve but since I
cannot use LMTP (and Director) on MX (but I have Director for POP/IMAP
access) the only way for not corrupting dovecot.index files is not
update their on delivery emails.
But reading http://wiki2.dovecot.org/MailLocation/Maildir this shouldn’t
be a problem (Optimizations “maildir_very_dirty_syncs=yes” … It's still
safe to deliver new mails to new/ …) since MX deliver new emails in
new/.
Is a Dovecot limit or is a problem of my configuration?
Thanks
