Well, we are running smail 3.1 there and not sendmail. However, I have
a sendmail.cf for an older Solaris sendmail that does what you probably
want.

I know that for sure; that is part of why I'm not using sendmail except
for a few (mostly Sun) sites.

The sendmail.cf that works is a modification of Sun's 'leaf' configuration
to use uucp for the default transport instead of ether, and to do
domain addressing instead of uucp '!' addressing.

I'll see if I have a copy on this machine and if so will send it here:
The changes from Sun's are the 'major relay mailer' ether->uucp,
and the rule numbers in the uux command line. I'll add #PAC comments
in the changed places...

NB O'Reilly's sendmail book is the thickest one in their entire sysadmin
series; there must be a reason :-)

# Name Canonicalization

# Internal format of names within the rewriting rules is:

# that the relevant host name could be on the front of the name (for
