dovecot-uidlist is not up-to-date
Hi,
Am using dovecot-2.2.10-8 on Centos-7 and everything seemed to be totally fine for many years. Now am trying to migrate our on-premises mail server to the cloud and I had to get some statistics. I was doing that using the doveadm utility.
Unfortunately I found that the numbers don't match if I check the real messages in my Maildirs. For some account doveadm was reporting number of messages but that account didn't have any messages stored at all.
So I looked a bit further and found that doveadm utility reports data form indexes and indexes are built using dovecot-uidlist data. For quite some folders these files have way more data than actual mailbox has. For example, my personal Inbox has 569 messages but dovecot-uidlist has 716 entries.
I don't know when and how that happened but this happens a lot on many different mailboxes on my server. I never touched dovecot-uidlist files outside of dovecot. I might have removed messages from Maildirs though, but not at this scale.
Now the question is if there's any way to tell dovecot to rebuild dovecot-uidlist files using actual Maildir data. I don't want to remove dovecot-uidlist files as this triggers the whole mailbox being re-downloaded by the imap client. With some accounts having over 100Gb of mail this is too much of a hassle. I just need dovecot itself to fix it's data.
Thanks,
Fil

doveadm index -A '*'
if that doesn't work then perhaps
doveadm force-resync -A '*'
of course you can use -u <user> for a specific user instead of -A for all users.

Tried that. It rebuilds index based on dovecot-uidlist. But not the dovecot-uidlist based on actual mail data. :(

Did you try removing the file?

Yes. That makes imap client to re-download whole mail folder. Not an acceptable solution to me :(

doveadm index -A '*' if that doesn't work then perhaps doveadm force-resync -A '*' of course you can use -u <user> for a specific user instead of -Afor all users.
