- Summary: uucp only connection to a relay host
- Keywords: sendmail.cf

- Hello !
-
- After hours of trying out different sendmail configuration options
- I found a way to tell sendmail to send mail (!local) to a mail host
- or relay host specified with the define DR.
-
- The sendmail.cf as being shipped with 386bsd 0.1 didn't work for me.
-
- Internet adresses via the Muucp mailer were treated as local
- addresses which couldn't be resolved.
-
- Building a new sendmail.cf from scratch using m4
- (see /usr/src/usr.sbin/sendmail/cf/cf/uucpproto.mc) didn't work
- properly, too.
-
- The reason is, that in the machine dependend part of rule zero
- (end of sendmail.cf) a line is missing to tell sendmail to send
- internet mail to a formerly specified relay host
- before finally trying to resolve the mail locally.
-
- Below is my sendmail.cf file. Changed or important lines are marked
- with ^^^^^^^^^^^^^^^^^^^
-
- Hope it's usefull.
- BTW: use it on your own risk ...
-
- Bye
- Andreas Klemm
