Hello,
If you set errors_to= for the local_user director/router, the uid of
the target given as argument for errors_to= is used for regular
deliveries.
This was reported by Michael Stuermer as
http://bugs.debian.org/184027
against exim 3.35 but also applies to 4.12.
Verbose:
-----------------
exim3:
#transport
local_delivery:
driver = appendfile
group = mail
mode = 0660
mode_fail_narrower = false
envelope_to_add = true
return_path_add = true
file = /var/spool/mail/${local_part}
#director
localuser:
driver = localuser
transport = local_delivery
errors_to = postmaster
-----------------
exim4:
#transport
mail_spool:
driver = appendfile
file = /var/mail/$local_part
delivery_date_add
envelope_to_add
return_path_add
group = mail
mode = 0660
#router
local_user:
driver = accept
check_local_user
transport = mail_spool
-----------------
The respective transport does not set any specific uid, the mail is
delivered as the user to which postmaster expands (uid 1001 is
ametzler)
