I've had my own domain, lets call it mydomain.com, for getting on for 25 years. In all that time, as a customer of Pipex, then Tiscali and now TalkTalk I've been able to send emails identified as coming from me@mydomain.com. As of a couple of days ago, I get this warning: "Sender address rejected: not owned by user 3@10880114.". So now I have set the sending email address to me@dsl.pipex.com to be able to send emails. What has changed and why?
