"let the bug"? The idea is anyway that you return
home=/var/mail/vmail/danjou.info/jd and set

mail_location = maildir:%h

That makes much more sense to me. I've considered making it an error to
return relative home dirs from userdb, but that might break some setups
that are actually working right..

Well, I guess there's some confusion about what a home dir is.. With
Dovecot the home dir is always what userdb returns as the home dir.
Dovecot doesn't care about /etc/passwd at all, unless your userdb is
passwd. So Dovecot doesn't know/care that deliver is run as "mail" user,
it doesn't care what /etc/passwd contains for the mail user.

It's probably the large mails that cause the problem. Dovecot writes
them to a temporary file under home directory.
