Oliver's quite right;  if you're claiming the email is from Gmail then
it really has to travel out via their servers.  A lot of the rest of the
world will check things like Gmail's SPF definitions, and any DKIM

    $ dig +short gmail.com txt
    "v=spf1 redirect=_spf.google.com"

says how to send mail to Gmail's SMTP server for it to send on.  It's
part of their information for configuring POP3 to receive email, but
it's useful standalone.  You do have to use TLS or SSL for the SMTP;  a
plain text connection won't do.  It looks like recent send(1)s support
-tls amongst other stuff.

Cheers, Ralph.
