- But of course you should not rewrite except based on what your direct
- neighbor requires. That's part of the definition of "gateway".

- That is one way. There are other attitudes. After a few years and
- hundred UUCP neighbors, some people get tired of reforming the world,
- and just let people do whatever they silliness they want within
- limits. Eventually you just pick a list of minimal requirements (e.g.
- name in the maps or registered FQDN, >= 2400 b/s modem unless news
- wanted, no more than a few bounces/week) and refuse connections unless
- unless those requirements are met.
