If LDAP is enabled in amavisd, a LDAP query for a boolean attribute
'amavisLocal' is implicitly prepended to the @local_domains_maps.

attributetype (
   NAME 'amavisLocal'
   DESC 'Is user considered local'
   EQUALITY booleanMatch

So for every recipient (his full e-mail address or just a domain
or subdomain part) this information is already obtained from
LDAP, you just need to provide this information. In absence of
this attribute from LDAP, the lookup continues the search through
remaining lookup entries in the @local_domains_maps list.

(and similarly for SQL, where a field name 'local' is queried)

So what you are asking is already there.
