I added this:
passdb {
driver = passwd
skip = authenticated
}
Which enables indeed local delivery, I also noticed this. Maybe the
password field check shoud not be done, when you enable skip
authentication?

Subject: Re: Local lmtp proxy on backend server
I receive a local mail when I do a 'mail test' on a backend svr1
with
this[0] configuration. However when I just add only one
configuration
change 'lmtp_proxy = yes' I am getting these errors[1]. I would
expect
this email to still be delivered locally, should this be working or
do I
misunderstand the lmtp proxy functionality?

PAM does not support looking up users, so you cannot use it for LMTP
proxying. Try adding
passdb {
driver = passwd
skip = authenticated
}
after PAM block.
