For domains listed in $mydestination if you want to accept mail
for only a subset of users listed in /etc/passwd you need to
change local_recipient_maps to include only the desired users.
You can leave out the unix:passwd.byname entirely:
local_recipient_maps = $alias_maps
provided you list all valid local users in either the aliases(5)
file:
# Identity mapping for local_recipient_maps!
joeuser: joeuser
or the virtual(5) file:
# Match bare joeuser in $mydestination or $myorigin,
# rewrite to "@localhost" for local delivery.
#
joeuser joeu...@localhost
#
# OR if you prefer comment above and uncomment below
# to rewrite to joeu...@$myorigin
#
# joeuser joeuser
Provided a recipient is listed in either aliases(5) or virtual(5)
mail will be accepted. Otherwise the recipient will be rejected
(given the above setting of local_recipient_maps).
