The default setting "local_recipient_maps = unix:passwd.byname

can I restrict it only to members of the specific group?
There is no such filter for /etc/passwd built into Postfix. Instead
of unix:passwd.byname, you could enumerate the users in a Postfix
table (hash, lmdb, ...).
Or, replace unix:passwd.byname with your favorite LDAP or *SQL query.
That's the thing actually. The server sees all the LDAP users but is
intended to only accept emails to a bunch of local non-LDAP accounts.
It's used for some automated log and report delivery and processing from
other sites (don't ask - obsolete system, can't change that, just need
the emails).
Right now Postfix is happy to accept email for all users in our LDAP
tree which I don't want. If I could make Postfix reject the LDAP
accounts and only accept for those in /etc/passwd that would actually be
enough for my needs as well.
Failing all that I would have to enlist all the users in a separate
file, oh well.
