Well, I know many ISPs block port 25 heading to their users' connections
in order to fight spam, but I don't see how an SMTP server would know
whether a client like Mozilla was connecting to it vs. Sendmail or Postfix...

Having looked at sniffer traces of both connections, I've not seen a
difference between Sendmail and Mozilla (for example).  That's how I
handle connecting to my ISP's authenticated SMTP server.
