I have a feeling that they do things like site!user@Sun.COM if the mail
is being sent to an Internet site. All the mail I've ever seen come through
Sun has had the Frmom: line converted into a pure bang path. Here's why

I'm IN a valid domain!! Yet, without fail, Sun will merrily butcher my
From: lines if I should decide to route something through them. No! No!

To spread the word. See, there's this mutual trust thing. All sites on
the UUCP net trust all the other sites to NOT do nasty things to mail
that's passing through. When a major player like Sun breaks this trust,
some people will want to tell everyone else about it.

Me, I just take pains to avoid Sun. It makes me happy since I don't
wind up with broken headers and it makes them happy since they don't
have to field my traffic.

I'm quite certain, though, that my mailer won't butcher the headers
of messages from Sun. I wonder if they appreciate that.
