I am using gmail as my email provider, and I only have gmail servers for my mx records. I don't like the 500 message per day cap. To address this issue I would like to run postfix on my Linux machine to only send email, port 25 blocked by my firewall. I can send email, however google marks all messages sent with postfix as SPAM. How do I make sure that people know email sent with postfix is valid?
