host masquerade in sendmail

[NatePuri <publisher_(_at_)_office_(_dot_)_ompages_(_dot_)_com>]

Hi all,

I'm trying to follow y'all advice on get my laptop's mail working correctly
and to stop have all my mail bounce.

I added the line

MASQUERADE_AS(office.ompages.com)

to openbsd-proto.mc and to tcpproto.mc

Now I can't send email at all.  What have I done wrong.

My host is laptop.ompages.com on an internal LAN and I want other hosts
to think that it is office.ompages.com which is my FDQN.  Thanks..

Which .mc file does the above line go in?

-nate
