Kirill, old friend!
I should point out a problem with Exim's behaviour in this regards:
Users will reglularly delete their IMAP folders, even "system" folders. As far
as I know, you can't protect folders in Courier, and I haven't been able to
think of any file permission trick to manage it either.
So you will have to rely on Exim creating the mail-sub-dir on delivery, if it
doesn't already exist.
Now, there is no way (as far as I know) to instruct Exim to treat this new
maildir as subfolder. Specifically, you can't get exim to create the necessary
"maildirfolder" file in the subfolder between creation and delivery. This means
that Exim will only check that particular maildir folder when it calculates
quota usage.
So direct delivery to maildir subfolders will break your quota system, if you
have one.
I think I've mentioned this on the list, didn't get any response.
