What you are wanting to do is configure Sendmail to relay messages for
specific domain(s) to your internal mail server(s).

1) Add the domain(s) that you want to relay messages for to your
relay-domains (class R) file.

2) Add entries in your Access DB for each valid recipient. I.e:
To:valid@domain.tld OK

3) Add a catch all entries for the domain(s) in question to REJECT
messages. I.e:
To:domain.tld REJECT

4) Set up a mailertable entry to tell Sendmail to relay messages for
the domain(s) to the internal mail server(s). I.e:
domain.tld relay:mailbox.domain.tld

5) Remove any stale config from any files not listed above.

This *should* get you the results that you are after.
