Mail is submitted with /usr/sbin/sendmail, and picked up with the
Postfix pickup daemon. There is no SMTP involved at all.

Now, you *can* configure PHP to use a different sendmail-like command
that connects to Postfix over SMTP. There programs are called
something like "mini sendmail".
It may also be possible to have PHP submit mail over SMTP. I haven't
looked at PHP in a long time, and then it had no built-in support.
