For incoming mail (i.e. you've got your own SMTP server processing your mail), your ISP must allow incoming connections on your local port 25. Most people interested in this method are involved in writing email-sending scripts, so I'll assume that you are too. It's actually almost the same as relaying email through your own SMTP server; this time, you find out what the remote SMTP server is and use that instead. Incidentally, this allows you to send email even if you don't have an email account or inbox. For outgoing mail, your ISP must allow remote connections to port 25, and this is most likely allowed.

I got 2 questions: Does it work if you have port 25 blocked by your ISP? and: Is there any program out there that can help me achieve sending this way? Thank you! Interesting article.
