All, have recently upgraded my RH9 mail server (Postfix) to Fedora Core 2, the one element that I overlooked is that Courier imap is replaced with the Cyrus package. I didn't like it so replaced it with Dovecot which mostly just works similarly to Courier.

However, I've lost all of my folders ! Having looked at many web posts about mail formats I'm now thoroughly confused and am making no progress.

As far as I can make out, I was using the mbox format, i.e. each folder is represented by a flat file containing all of the messages. In my home directory I had (was using Thunderbird client) ...

~/inbox
~/Drafts
~/Junk
~/Sent
~/Trash

and also (server hostname is wodin)...

~/Wodin

Underneath this was all my archive ...

~/Wodin/misc
~/Wodin/stuff
~/Wodin/fedora
~/Wodin/lug

etc


How can I migrate these flatfiles so that now I'm using Dovecot I can reintegrate my folder structure and the archive ?

(added edit to mention Postfix, thought it might be important :-) )
