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.
