Your gateway needs a table of valid recipients, the domain in question
is presumably configured as a "relay domain" by being listed in
$relay_domains. If you don't want to have identity mappings in
virtual_alias_maps, you need to add entries to relay_recipient_maps:
main.cf:
# Use "cdb" if you have it.
default_database_type = hash
indexed = ${default_database_type}:${config_directory}/
relay_recipient_maps = ${indexed}relay_rcpts
relay_rcpts:
[email protected] valid
...
where the word "valid" on "the right hand side" of the table can be
replaced by any non-empty value that makes sense to you. Postfix
only needs the lookup key to map to a non-empty result.
This said, the identity virtual_alias_maps mappings are a fine way
to achieve the same result. The lookup will be done anyway, and you
already have a virtual alias table, so it may in fact be simpler to
keep using the identity mappings, but you MUST make sure that
relay_recipient_maps (assuming the domain is a relay domain) is
set to some table (be it one with no entries).
main.cf:
# All relay recipients are listed in virtual_alias_maps, so just
# create and "postmap" an empty file.
#
relay_recipient_maps = ${indexed}empty
