We went through this when I was at NCR and we had to talk to both "smart"
(domain) routers and "dumb" (bang) routers.  The "more correct" version of
the From_ line is to use:

     From <NodeName>.<DomainName>!<UserName> blah remote from <NodeName>

This gets transformed into <NodeName>!<NodeName>.<DomainName>!<UserName>
at the receiving site. Dumb UUCP "bang" routers are happy, since they just
look at the leading <NodeName> for routing, and smart routers are happy,
since the full domain name is present for them to optimize.
