I've written a small chapter how-to configure exim for use with UUCP
(mostly condensed from the exim-user mailing list plus some experimenting)
and would be glad if it could be included in the exim documentation.

@section Exim and @sc{uucp}

Configuring exim for use with @sc{uucp} is a bit of manual work, since exim
wasn't written with @sc{uucp} in mind.

This guide assumes that you use @emph{Internet-addressing} --- i.e. both
sides use Taylor-@sc{uucp} --- or 1-level deep Bang-paths (the Bang-Path level 
has to be finite to make address-rewriting feasible). What you have to do is 
the following:

@enumerate
@item 
add a new transports definition
@item 
add a new router
@end enumerate

@subsection Transports

The @emph{transports} does the work: it passes the mail to @sc{uucp}.
This is the place to do bang-path-conversions and similar things
(when using Taylor-@sc{uucp}, as my provider does, the Internet-address 
is simply passed to rmail).        

@example
uucp_pipe:
  driver = pipe 
  batch = all 
  command = "uux - -a\"$sender_address\" -r $host\!rmail $pipe_addresses" 
  delivery_date_add = true 
  pipe_as_creator 
  restrict_to_path 
  path = "/usr/bin:/bin" 
  return_output
@end example

If you wanted to use bang-paths, you'd use something as (untested):
@example
@dots{}
  command = "uux - -a$sender_address -r $host\!rmail ($domain\!$local_part)" 
@dots{}
@end example

@subsection Router

The @emph{router} tells exim that a @sc{uucp}-route is available:

@example
uucp:
  driver = domainlist 
  transport = uucp_pipe 
  route_list = "* neighbor byname"
@end example

@var{neighbor} is the upstream @sc{uucp}-neighbor; all outgoing traffic
is routed over there (leaf node configuration).

@subsection Other

In order to omit the @code{Sender: uucp} line, add @var{uucp} to the
trusted users:

@example
trusted_users  = mail:uucp
trusted_groups = uucp
@end example

@bye
