I have set up a web server and trying to get an email server working(using squirrelmail,wamp and hmail.)Whenever i try to send the email i get the following error message.
'The IP you're using to send email is not authorized...'
And the mail is not sent.I have a no ip account which is used for dns hosting.I have tried using the spf wizard there but i am not sure whether it succesfully updated or not.What can i do to overcome this problem.
