Yup. Two ways, in fact.
I) use md_check_against_smtp_server to validate the recipient address.
and/or
II) build a sendmail "access" file based on directory listings from the
downstream mail servers. These would look like
[EMAIL PROTECTED] OK (or RELAY)
[EMAIL PROTECTED] OK (or RELAY)
...
@sitea.example.org REJECT (no unknown users @sitea.example.org!)
[EMAIL PROTECTED] OK (or RELAY)
[EMAIL PROTECTED] OK (or RELAY)
...
@siteb.example.org REJECT
[EMAIL PROTECTED] OK (or RELAY)
...
@example.org REJECT
II) has nothing to do with MIMEDefang and is a purely sendmail technique.
Depending on internal connection speed vs. email longevity one or the other
approach might be better for your particular network.
