I tried a test yesterday of converting my inbox on the gb server to Maildir (preparation for migrating all the mailboxes) and it would appear that the debian dovecot then decides to use that created maildir as it’s default location. I was wondering where all my other folders had disappeared to, then I noticed that there were twice as many messages as there should have bene – along with I tried the conversion twice to see if it duplicated messages, which it did.
