I don't think I changed anything special in there..

Mail directory shouldn't be relative. Also it'd be better not to rely  
on Dovecot's autodetection of mailbox format. Change it instead to  
something like:

.., concat('maildir:', homedir, '/', maildir) as mail, ..

Maybe I should change the code so that relative paths are guaranteed  
to work, or guaranteed to fail. Currently I'm not sure why it would  
or would not work.
