In mail from mrm@Sceard.COM I received a copy of the headers from a message
I had sent to him earlier.  I know that the From: line left chinet looking
like:  From: les@chinet.chi.il.us (Leslie Mikesell)

What he got was: 
 From: Leslie Mikesell <ucsd!gargoyle.uchicago.edu!chinet.chi.il.us!les>

Are we having fun yet?

Not always - you may want to mail to a site where modems aren't available
(or allowed) or you may have no common communications protocol.
