I've got a crash in dovecot-imap when trying to list the inbox on a nonexistant directory. I'm not sure how it should be handled, but basically it's only happening when the directory in imap's MAIL environment doesn't exist.
This is a problem for me because I'm trying to have dovecot create all the necessary directories in the specified environment, as I don't know if the user will pop/imap or recieve an email first, and the dir needs to either be already ready, or created upon reciept. I've already got postfix to create a ~/Maildir when a new mail comes in, but for my migration plan to work, I need dovecot to create this directory instead of segfaulting. ;)

If I use MAIL=maildir:/tmp/nonexistant, it crashes, but what I'm really trying to do is MAIL=maildir:/home/staff/%u/Maildir/, which will necessarily be nonexistant, and I'd like to see dovecot create this in the manner that postfix does; with the logged in user's uid/gid.
Now, if I leave default_mail_env blank, and let dovecot's autodetection do the work, it seems to create a maildir in ~/mail. This works just fine, except it's the wrong directory.
Otherwise, dovecot rocks, and in another, less automatic setup, I've been using it for the better part of a year with nothing but happy results, and appreciate your work. (Irssi too :)
