Today I tried to import mail directly on the server's home directory on the server. I copied it directly. I didn't use the imap protocol. Dovcot didn't recognize these emails. I didn't display these imported emails on my page, recalculating disk quotas. It will not increase the used capacity. I try to send an email to this user, dovcot recognizes all the emails, and recalculates the disk cooperation, this time is correct.
Why can't I identify the mail I imported?
