In order to (sucessfully) run a mail server, you need to use a static, business class IP connection. Without that, you are most likely to run into problems like DNS BL listings, DUL listings, and of course, your ISP is blocking outbound port 25 to make sure that you can't run an outbound spambot. side affect is you can't run a smtp server either. you COULD use some of the workarounds (sending to yahoo on 587/? 465?) there are FAQ's and lots of information on the internet on doing this with postfix. ASK IN THE POSTFIX DIRECTOR.
