Neither of dovecot.index files are created (.cache, .log, .thread) - these files are created when I open the folder with IMAP client. When mailbox is not used for long time, the indexing takes very long time. So I'm looking for any solution (preferably with doveadm) to manually reindex folders in background.

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

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 "*"'.
