Hello,

I'm using maildirs, and I have problems with big mailboxes (~ 20000 emails, 30-50GB) - sometimes access to such mailbox takes very long (~10 minutes), I would like to be able to create index for mailbox in background, but I couldn't find any way to do it. So far I tried:

doveadm -D -vvv index -u user 'Folder'

But even if this folder have no dovecot.index* files - I always get:

doveadm(user): Info: Wersje robocze: Cache is already up to date

It seems that doveadm doesn't actually checks if the index is present. The index is created only when I log with IMAP client and check the folder.

So i tried:

doveadm mailbox cache purge -u user 'Folder'

No joy either:

doveadm(user): Error: Cache is unusable

And command below doesn't actually do anything to index:

doveadm -vvv force-resync -u user 'Folder'

Is there any way to use doveadm tool to create/fix index? Shouldn't the index be updated on each email arrival?

Cheers,
