Ah, but you're wrong, Laser Lips.  8-) The Amiga does indeed have a mail
utility, but it's not written by CBM.  I refer, of course, to Matt Dillon's
UUCP system, complete with UUCP, Netnews, _AND_ mail.  Works fine, lasts a
long time.

Yes, it can.  I'll explain.  A path (address) containing "!" characters (we
call them "bangs") describes a path from system to system that is used by the
uucp (Unix-to-Unix-CoPy) program.  The first path above says that the message,
somehow must get to "someplace" then to "somehow" and from there it goes to
uunet.uu.net and into the mailbox of some user named "guy".  This path is
called "mixed mode", since it uses the bang path and an Internet-style domain.
Most mailing programs have major problems using mixed mode addresses.

The second path above is merely an Internet-style domain address.  It assumes
that your software knows how to send a message to "somewhere.here" (it looks
it up in a map database and builds a bang path to get it from point A to
point B, but you never see that happen.  It's "magic".)  Once it gets
to "somewhere.here", it goes into the mailbox of user "ad897963-dads3" on
that system.

If you look at my .signature below, you'll see two different addresses, one
for the system here at the office (tmiuv0!rick) and one for the Unix box
(and eventually my A3000, that is the xyclone!sysop address).  The first line
of the address is the uucp bang path, which assumes that you know how to get
a message to the system "uunet".  The second line has the equivalent Internet
domain address.

This really belongs in the comp.mail group.  But, you knew that already.
