Newbie needs help!

[Leo Gonzales, Jr.]

Hi,

I don't know much about sendmail and I need to configure it for our company.
It seems that I can send messages to some other hosts and not to others. The
message I get back when it fails is shown below. Can someone tell me how I
can solve this problem?

Note: I'm running RedHat 7

The message seems clear enough - gauguin.xcelcis.com does indeed not
exist (in the global DNS) - you can't send mail with such a sender
address. Perhaps you need to use MASQUERADE_AS(`xcelcis.com') and
FEATURE(`masquerade_envelope') in your .mc file, see cf/README (might be
/usr/lib/sendmail-cf/README on RedHat, and might require that you
install the "sendmail-cf" rpm).
