There is nothing you can do about it. If those services refuse to accept mail from you that is the end of the story. If you want to run your own mailserver from a dynamic IP address you should configure Postfix to relay all your outgoing mail through your ISP’s mail server. It has a static IP and (hopefully) good reputation. You can still recive mail directly from the net. Relaying applies only to outgoing mail, adding an extra hop to each message. -- Cheers Petri GSM +358 400 505 939
