-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Actually, we don't at all care what mail ports on the ISP's address are listening. What we do care about is if he can send mail to other servers besides his ISP on port 25. You can determine that for example as follows: telnet speech.braille.uwo.ca 25 If speech.braille.uwo.ca responds, then he doesn't need to use his ISP. If speech.braille.uwo.ca doesn't respond, then he's limited to using his ISP to send mail, unless he can find someone else to relay through. Even if he can send mail by himself, he still may not be able to send it to every server if he's on a dynamic IP, as someone else has already pointed out.
