I need help to resolve a Postfix server.
Initially the server was using POSTFIX defaults, witch resulted in being blocked in all major ISPs (google, hotmail, yahoo, etc), cause my system can deliver up to 200k emails per hour to Postfix, and Postfix with default settings is too gready and gets blocked everywhere for sending too fast.
Now the server is sending email too slowly, and it is still blocked at hotmail.
I will pay for postfix configuration proved to work with all of these domains.

I think it will be easy for somebody who know linux :). There is some infected pc in your network or your server is hacked or you have open ports to send email through your server.
