I set my client's computer email account up (TalkTalk email account) and I accepted to choose the opton that configured it automatically for Windows Mail. I have sent her a couple of test emails that she can get, but when she's clicked Reply, writes me an email, and clicks Send, I don't get any emails from her. However, it works with all the other addresses in her address book. Windows Mail even told her that my yahoo.co.uk email address didn't exist! Why is this?
