the safest quick choice is to convert to mbx format mailboxes; procmail
can't deliver direct to this format but you can use dmail in a procmail
recipe to do the delivery.
This is how I think this works, but I'm only about 95% sure of it.
To actually create a mailbox in mbx format, do this in a shell:
mailutil create "#driver.mbx/junkmail"
To deliver to said mailbox, something like this procmail recipe should work:
:0
| dmail +junkmail
You may have to play around with directory paths and such.
It is important to do the creation part; otherwise dmail will autocreate
the folder for you but will make it an mbox file.
I don't know what happens when you create a new folder in an imapd session.
I'm betting you get an old mbox style folder.
I am not aware of a way to get dmail to automatically create folders in
mbx format. Probably a compile-time option in c-client. Or maybe you can
use some option in the /etc/c-client.cf file but that is fraught with peril.
