First bit:
I'm not totally sure that I understand but I think that you probably mean that your PC is trying to make a dial-up connection, even though you've already got a broadband one. This is a common problem when people switch to broadband. ISPs often forget to tell their customers to change the settings which are shared by Internet Explorer and Outlook Express. Here's how to fix it:
Go to Tools > Internet Options > Connections.
Click to place a dot next to 'Never dial a connection'
Click 'Apply' and then 'OK'.
Second bit:
Your reference to your 'old e-mail address' suggests that you've changed your ISP but not configured your new e-mail address in Outlook Express (or whatever other e-mail client you might be using). When you leave an ISP, they normally allow you to continue connecting to the e-mail server which handles your incoming mail (either indefinitely or sometimes only for a month or two) but you can no longer connect to the outgoing mail server. That would explain why you're still getting mail sent to the old address.
To set up your new account, you should open your e-mail client (which is probably Outlook Express) and go to Tools > Accounts > New > Mail.
Now fill in the relevant details for your account.
The incoming mail server should be pop.tiscali.co.uk
The outgoing server should be smtp.tiscali.co.uk
The account name should be your
full e-mail address (not just the bit before the '@' sign).
That's probably sufficient information for setting up the account (apart, of course, from your password) but further details on the required settings can be found here:
