	If you really need the Gmail certs, you can use this to get them:

	openssl s_client -connect smtp.gmail.com:587 -starttls smtp -showcerts

	If you feel you really need the "Equifax Secure Certificate Authority"
	pem, go here <http://www.geotrust.com/resources/root-certificates/> and
	download it.

	Again, how to set up Sendmail is a task I leave for the student.

Jerry, Matthew, thank you

I think I got it working.
In addition to your advice, this guide was very helpful:


It seems these two options were required:

define(`RELAY_MAILER_ARGS', `TCP $h 587')
define(`ESMTP_MAILER_ARGS', `TCP $h 587')

Thanks again
