[nos-bbs] JNOS return to sender

[maiko at pcsinternet.ca]

Have you tried to actually put in a refuse in your rewrite, but using
the fully qualified address, for instance :

    ve4klm at ve4klm.#wpg.mb.can.noam  refuse

The key I suppose would be to find the correct spot in rewrite to put
this so that it does not get processed first and 'shortened'. I will
play with this, the SMTP code suggests that something is possible.

It might just require a tweak then, since accepting messages is a
standard thing, it's just we might have to do a minor change in the
delivery part. Will let you know what I find.
