I am trying to build a web server in my home. I have static IP address and my web server works really nice but my mail server is not. I also want to send mails from my computer but my ISP is blocking port #25 . I tried to use port #587  and set the important settings but my mail server POSTFIX is trying to connect other mail servers (like google's or msn's) over port #25. How can i achieve this. I have made hours of searches on internet but i could not solve my problem. I am a real newbie so i need help very much.

Thank you,
Caner
