I have just bought a new notebook Presario CQ61 model CQ61 - 406TU with windows 7. I have installed Thunderbird but it keeps telling me that OPTUS will not allow access. I am able to get my email from OPTUS webmail, so i know my log in info is correct. I do nor want to change my IP, I do not want to have to change my email address. any suggestions? Thanks in advance for advice.
