I am getting this error code with windows live mail on my new netbook, but only on outgoing messages, I am recieving incoming fine. I have checked the settings for the outgoing mail SMPT server, and the other account settings. They are exactly the same as my other laptop. I have tried googling for the answer, but they just suggest a registry cleaner called reg edit (I'm a bit suspicious of this)

I'm not very techy, so please use idiot proof language.
