Sending mail or news via UUCP
-----------------------------

   When mail is to be sent from your machine to another machine via
UUCP, the mail delivery agent will invoke `uux'.  It will generally run
a command such as `uux - SYSTEM!rmail ADDRESS', where SYSTEM is the
remote system to which the mail is being sent.  It may pass other
options to `uux', such as `-r' or `-g' (see Invoking uux.).

   The news system also invokes `uux' in order to transfer articles to
another system.  The only difference is that news will use `uux' to
invoke `rnews' on the remote system, rather than `rmail'.

   You should arrange for your mail and news systems to invoke the
Taylor UUCP version of `uux'.  If you only have Taylor UUCP, or if you
simply replace any existing version of `uux' with the Taylor UUCP
version, this will probably happen automatically.  However, if you have
two UUCP packages installed on your system, you will probably have to
modify the mail and news configuration files in some way.

   Actually, if both the system UUCP and Taylor UUCP are using the same
spool directory format, the system `uux' will probably work fine with
the Taylor `uucico' (the reverse is not the case: the Taylor `uux'
requires the Taylor `uucico').  However, data transfer will be somewhat
more efficient if the Taylor `uux' is used.
