@local_domains_maps is newer. The default value is:
This is shown in amavisd.conf-default (included with the source code)
which illustrates all the default values.
This is from amavisd.conf-sample (no longer provided with 2.7.x or newer):
# Lookup list of local domains (see README.lookups for syntax details)
# @local_domains_maps is a list of lookup tables which are used in deciding
# whether a recipient is local or not, or in other words, if the message is
# outgoing or not. This affects inserting spam-related and OS fingerprinting
# header fields for local recipients, editing Subject header field and allowing
# mail body defanging, limiting recipient notifications to local recipients,
# in deciding if address extension may be appended, in matching mail addresses
# to non-fqdn SQL record keys, for proper operation of pen pals feature,
# for selecting statistics counters (distinguishing outgoing from internal-
# to internal mail), and possibly more in future versions.
# Set it up correctly if you need features that rely on this setting.
# With Postfix (2.0) a quick hint on what local domains normally are:
# a union of domains specified in: mydestination, virtual_alias_domains,
# virtual_mailbox_domains, and relay_domains.
@local_domains_maps = ( [".$mydomain"] ); # $mydomain and its subdomains
# @local_domains_maps = (); # default is empty list, no recip. considered local
# @local_domains_maps = # using ACL lookup table
# ( [ ".$mydomain", 'sub.example.net', '.example.com' ] );
# @local_domains_maps = # similar, split list elements on whitespace
# ( [qw( .example.com !host.sub.example.net .sub.example.net )] );
# @local_domains_maps = ( new_RE( qr'[@.]example\.com$'i ) ); # using regexp
# @local_domains_maps = ( read_hash("$MYHOME/local_domains") ); # using hash
# perhaps combined with Postfix: mydestination = /var/amavis/local_domains
# for debugging purposes: dump_hash($local_domains_maps);
