Hi,

I finally migrated my IMAP server from cyrus to dovecot2. I have been using cyrus since many years and have not much experience with dovecot yet though.

I've converted my imap server using cyrus2dovecot (several times until I thought it was correct) but there is one thing left which confuses me and I'm not sure what I can or need to do to change it.

With Cyrus I used unixhierarchysep: yes and subfolders within Cyrus are always below INBOX.

I'm used to that in my IMAP clients and wanted to preserve it with Dovecot. So during migration I finally made sure to create the subfolder again below INBOX wich looks fine in Thunderbird for example. But my mobile devices (Android based with K9) were displaying the folders with Cyrus just with their name w/o the INBOX prefix. (Mobile clients are bad in displaying folder hierarchies so it was convenient to have them looking like they were in parallel to the Inbox.) Now I get the folders displayed as INBOX.whatever and my Android mail clients fail to map them to the special (and localized) folders like Trash. While that seems consistent to my current hierarchy it's not what I wanted.

So basically my two questions are: them besides Inbox?

• Can I configure Dovecot in a way that it looks like Cyrus? Having subfolders below Inbox but let clients like those on Android display

• If that's not possible, can I move the subfolders up one level so they are next to the Inbox? How would I do that?

Sorry for the beginner questions. I played around with Dovecot before but using it in production environment disclosed some fine differences.

Thanks, Wolfgang
