First question you need to have answered is does your ISP allow outbound SMTP traffic. Mine happens to (Qwest), so I have daily reports mailed from my home server to my gmail account. Once you have answered that, if postfix is setup, you should be good to go. Postfix does a MX lookup for the destination email address (gmail.com, for example), and sends to one ofthe IPs listed.The only thing you might have to additionally set up is a reverse DNS entry. Dynamic DNS hosting, such as dyndns or no-ip.com are free for this kind of set up. You may need this because many mail servers do a reverse lookup of your IP when they accept mail to make sure it is coming from yourdomain. Meaning, I send an email from my lin box from mydomain.com, my IP needs to map back to mydomain.com.
A simple way to test for allowed SMTP traffic is to telnet to you test destination. Get the IP by doing a dig or nslookup: 1. dig -t mx gmail.com 2. Jeremiah E.
