I haven't set maildir_use_size_file because our IMAP server (dovecot)
doesn't support it. So when using it, exim would add the size of each
new message, but dovecot wouldn't subtract deleted messages. So in the
end a mailbox wouldn't accept new messages although it might be empty.

This isn't possible with dovecot.
This is INBOX:
cur
new
This is Trash:
.Trash/cur
.Trash/new
This is Office/Boss
.Office.Boss/cur
.Office.Boss/new
So the maximum is two levels.
