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 -- Dmitry Filonov Network Analyst 300 Longwood Ave. Enders-1262.2 Boston, MA 02115 617-919-4702

Tried that. It rebuilds index based on dovecot-uidlist. But not the dovecot-uidlist based on actual mail data. :( Fil On March 21, 2018 11:58:21 PM EDT, "@lbutlr" <kremels at kreme.com> wrote:>On 2018-03-21 (17:15 MDT), Dmitry Filonov ><filonovd at enders.tch.harvard.edu> wrote: >> Now the question is if there's any way to tell dovecot to rebuild >dovecot-uidlist files using actual Maildir data.
