Controlling 'From' in mail headers? Help!

[Peter Espen]

        I have a uucp connection to a machine that has access
to the internet.

        How can I get the 'From' address in my outgoing mail headers
to reflect an internet address instead of a banglist address that
shows the entire path that my message has taken?

        For example, if I send an outgoing message on my machine, it
is que'd for the internet connected machine with a 'From' line
that looks like:

        uucpmachine!peter

When this message goes out from the internet connected machine, the
'From' line in the header looks like this:

        netmachine!uucpmachine!peter

I want it to look like this:

        uucpmachine!peter at domain.com

so that people who get my message down the line will be able to
reply to  'uucpmachine!peter at domain.com'  instead of a long list
of uucp connections that they have to follow to get back to me.

        The sysop and I can change the sendmail configuration on the
internet connected system if that is what is needed, but we need help
on figuring out what to change!

        Anyone?
