Daniel,
I have done this on my Unix and Linux boxen.
One reply mentioned the Dm section in sendmail.cf . . . it is
actually DM (both upper case letters) DM defines a Masquerade host.
In addition to the other solutions already provided in previous
replies, you may need to hack sendmail.cf. (probably
/etc/sendmail.cf or /etc/mail/sendmail.cf depending on what
version of sendmail you are running.
Install all the hacks that Gregory Hicks had in his reply, then:
Look for the "Format of headers" section. there will be a line
that looks something like:
HReceived: $?sfrom $s $.$?_($?s$|from $.$_) $.by $j$?r with $r$. ($v/$Z) id
$i$?u for $u$.; $b
The host name is given by the $j and the (8.8.8+Solaris/8.8.8) is in
the ($v/$Z). You can change or remove either or both. You could also try
changing the $j to $M to use the masquerade host.
You can take out the host name, but if the upstream computer can
resolve your IP address, it will put your host name in it's received
line.
The suggestion to use

This would remove the Received line, but it has to be done on the mail
server.
