Sorry to reply to myself... but to clarify my off-topic post...

define(`SMART_HOST', `mail.isp.net') by itself will send via port 25 and 
is good if you want to send via Comcast's servers.

If you want to send via another server and port 587, you want both

	define(`SMART_HOST', `mail.isp.net')
	define(`RELAY_MAILER_ARGS', `TCP $h 587')
