    I have 2 pc's linked with a cross-over cable.The main pc connects to the internet with adsl modem.
    Both PC's run winXP Pro.The internet connection sharing works fine.
    Both pc's has a seperate e-mail account.
    The main PC works fine with no hassles.
    The second pc can receive mail without problems but I cannot send mail from this pc.
    I get a message: "server response 551 :Sender adress rejected:Domain not found,Port25,Secure SSL:no,server error:551,Error number : 0x800ccc79

    I phoned the ISP and they confirmed that the smtp address is correct as well as the username and password.
    Is there any other setting that must be changed to make the second pc able to send and receive on its own account?
