dovecot - Dec 2019 - Dovecot 2.3.8 - How to force index creation for user/mailbox?

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,
TomekL

Try first 'doveadm fetch -u victim body ALL'. If this does not produce
any useful results, try 'doveadm force-resync -u victim "*"'.

Thanks, but both commands didn't create dovecot.index. Only when I open
folder with IMAP client, the dovecot.index is created.
