[comp.sys.att] WIN TCP/IP on Unix PC and Usenet gateways

brant@manta.UUCP (Brant Cheikes) (09/17/87)

I'm trying to get an AT&T Unix PC running WIN TCP/IP to act as a mail
gateway between Usenet and a TCP-based LAN.  For example, assume the
gateway Unix PC is called "gateway", and my machine "manta" is one of
its Usenet neighbors.  Say host "foo" is accessible to "gateway" via
TCP.  The gateway and all its TCP neighbors run sendmail, its Usenet
neighbors just have HDB uucp.

I would like to be able to send mail from manta to user "bar" on host
"foo" through node "gateway", presumably using the syntax gateway!foo!bar.
User bar should be able to reply to manta!brant@gateway.

The question: what's involved in arranging this?  I figured out that
/bin/rmail had to be linked to something besides /bin/mail, since mail
doesn't know from TCP; I tried linking rmail to /usr/lib/sendmail, and
that worked, sort of.  There were two problems: gateway couldn't grok
uucp addressing style for TCP hosts, i.e., foo!bar was a losing
syntax.  If I sent mail from manta to "gateway!bar@foo" (my mailer
does not assign higher precedence to '@'), uucp would rmail to
bar@foo, and gateway handles that fine.  Unfortunately, then user bar
gets mail with a return address of "uucp@gateway", completely losing
any reference to manta and/or brant.

I won't go on... the point is, if you have such a configuration
working (even if Unix PC's aren't necessarily involved), where you're
using WIN TCP/IP to gateway Usenet/TCP mail, I would very much like to
hear from you.  Thanks!
