First and foremost, I have my own domain at one.com and therefore my own pop3 server for receiving mails. I'm using windows Live as a email program on my computer. Firstly I set it up on my Desire, with the pop3 server I use in Live on my computer as ingoing mails, and the smtp I got from my ISP. It turns out that I can see the mails I receive, but I cannot send mails, on my phone. I find out that the outgoing server must be named, when using one.com; customer-smtp.one.com. I change my outgoing server to that one, and finally I can send mails from my phone. But now I can't receive / see the received mails on my phone anymore. It still works on my Windows Live, I just don't see them on my phone. What's the reason for this, and what can I do?
