          You can simply delete index file by hand and dovecot recreate it. If index size so big because of some fault, recreated one will be significantly smaller. If recreated index become the same size then this size is exact size it should be.



          Index size is dependant on the size of mailbox and can be really large if Full-Text Search aka FTS is turned on.

          • I know it (I can delete indexes and Dovecot will recreate them), but I have over 1 thousand email and deleting the index files by hand is not a solution. I was thinking Dovecot developers thought a config to do this step automatically to avoid extra disk usage in the server. As it seems they didn't it.
