- Yes, both can be. Create a "mailer" which checks the
- originator's address and bounces the mail if it's not
- authorized to use the link. If the originator is allowed to
- use the link, then just pass it along to uucp as usual.
-
- The problem with this is that if you have multiple UUCP links,
- and a message could be sent via a link which avoids PSI,
- sendmail and smail won't be able to figure that out for you.
- What I do is run MMDF. It has quite sophisticated facilities
- to support the implementation of policy-based routing, so you
- would only have to bounce mail for which there is _no_ valid
- route, and not all mail which is not permitted to use the best
- route.
