Hi Noah,

I'm going to blindly assume that you're using RedHat, or at least
that your sendmail setup is the same as on RedHat (otherwise,
you're on your own!)

Let's start simple - genericstable is really more useful if you've
managing email for multiple hosts.

Move to /etc/mail

Edit sendmail.mc and add (not the odd quotes!!!!):

    MASQUERADE_AS(`blah.com')dnl
    FEATURE(`masquerade_envelope')dnl

Then, rebuild sendmail.cf:

    make

Here, you may need to copy this new sendmail.cf over the old
one if the 'real' one isn't kept in /etc/mail.  Look to see
if you have the file /etc/sendmail.cf.  If so, then:

    cp sendmail.cf /etc

Restart the sendmail deamon:

    service sendmail restart

Test it!

Good luck,
Steve
