SMTP is best, especially if you are running any content-filers that you may be bypassing on your Postfix pickup service. I simply use localhost (127.0.0.1) on port 25. If SquirrelMail is running on the Postfix host, no need to direct SM to use port 587, since you are already authenticating uses to SM. Also, if you are running any content-filters, make sure that you do your DKIM signing at the last stage of the process, just before Postfix delivers the message to the recipient mail server.
