Yes there is:

Special handling of optional LDAP attribute 'amavisLocal'
---------------------------------------------------------
A special shorthand is provided when LDAP lookups are used: when a match
for a recipient address (or domain) is found in LDAP tables (regardless of
attribute values), the recipient is considered local, regardless of static
@local_domains_acl or %local_domains lookup tables. This simplifies
life when a large number of dynamically changing domains is hosted.
To overrule this behaviour, have an explicit boolean attribute 'amavisLocal'
with a value of True returned for each local domain, and False for other
domains which might be present in LDAP for some reason, but are nonlocal.
In general LDAP lookups are similar to SQL lookups except for the low level
LDAP/SQL specific code. The overall functionality, lookup rules, etc. are
identical.
So, it usually suffices to just provide any attribute for each local
domain, and defaults will suffice.
