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 useruser@example.com field value uid 12345 gid 12345 home /path-to-mailboxen/example.com/user mail maildir:~/Maildir:INBOX=~/Maildir quota_rule *:storage=0and

Hi Toni,
Try this:
mail_home = /path-to-mailboxen/%d/%n mail_location = maildir:~/Maildir:LAYOUT=fs
and
namespace inbox { separator = / prefix = inbox = yes subscriptions = yes list = yes type = private hidden = no }
