My father is having problems with his e-mails. Over the last few weeks he has noticed that several haven't been arriving at their destinations. I've sent a load of test e-mails from his e-mail address to a few of my e-mail addresses. Around 80-90% of them arrive at their destination, but some don't. Even days later there are still several that have just disappeared!
So if you have Orange Home Broadband would you be able to send some test e-mails from Windows Live e-mail using an Orange SMTP server particularly to a hotmail address as that would appear to be where most of the missing ones end up (or don't as the case may be!).
