This shows that the database lookup works. The intended effect should be
that the message is delivered to
/path-to-mailboxen/example.com/user/Maidir/new

And this shows that dovecot-lda just ignores the result.

In /etc/postfix/master.cf, I have this to call it:
dovecot unix - n n - - pipe
flags=DRhu user=_mailbox argv=/usr/lib/dovecot/deliver -f ${sender} -d ${user}@${domain} -a ${recipient}
Try adding
mail_privileged_group = mail
I am not sure why you recommend this. I never ever want to deliver to
/var/mail, and my mailbox directory has group 'mailbox' - hence I have
mail_privileged_group = mailbox
in my configuration.
My question is why this thing wants to deliver to /var/mail, despite
having a different location from the userdb, and how I can force it to
use the location from the userdb.
Thanks,
Toni
Sorry, I misread your problem..
can you try checking output of
`doveadm user <username>`
# doveadm user user@example.com
field value
uid 12345
gid 12345
home /path-to-mailboxen/example.com/user
mail maildir:~/Maildir:INBOX=~/Maildir
quota_rule *:storage=0
and
`doveadm auth lookup <username>`
# doveadm -v auth lookup user@example.com
passdb: user@example.com
user : user@example.com
Also, including `doveconf -n` would be useful.
