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

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
