Okay, so I did this:

1. cd /usr/share/sendmail/cf/cf
2. cp sendmail-slackware.mc newsendmailconf.mc
3. [edited newsendmailconf.mc adding the MASQUERADE_AS line]
4. m4 newsendmailconf.mc > /etc/mail/sendmail.cf
5. [rebooted rather than restarting sendmail, just to be on the safe
side ]

Now my /etc/sendmail.cf has a new line in:

DMourcompany.com

However, I'm still having the same problem. Outbound mail is still
stamped '@hostname.ourcompany.com' rather than just '@ourcompany.com'.
Can anyone offer any advice on how to fix it?

Cheers
