RedHat6.0+ (with all .rpm updates)

Add:
MASQUERADE_AS(real_domain.com)
MASQUERADE_DOMAIN(real_domain.com)
FEATURE(`masquerade_envelope')
dnl EXPOSED_USER(`root')dnl

to your /etc/mail/sendmail.mc file
Then convert the m4 to a .cf with
m4 /etc/mail/sendmail.mc > /etc/sendmail.cf

(This assumes you have the sendmail-cf package installed)

Then reatart sendmail : service sendmail restart

debian (sid but should also work on woody, not sure about potato)
Add:
MASQUERADE_AS(real_domain.com)
MASQUERADE_DOMAIN(real_domain.com)
FEATURE(`masquerade_envelope')
dnl EXPOSED_USER(`root')dnl

to your /etc/mail/sendmail.mc
Then convert the m4 to a .cf with
sendmailconfig
Answer yess to all the questions
This will also restart sendmail.

HTH

Yours Tony.
