How do I connect a second email address to my yahoo sky account

[jayach]

So why does it have that strange name as its description? 

I'm not an Apple user (shudder) but have you been into Mail Account Settings and entered a password as requested?

Is it possible it is the SMTP server that it is asking for a password for, as that says "optional"? (whatever that means, must be an Apple thing)

Personally I would remove the account and add it again

Where it says description, it automatically puts yjyarl.co.uk in there when I input the other details

Can you not delete it ?

[howie2008]

When deleting the YJYARL it then shows this i  need to be able to send and receive emails for the email address that I'm wanting to add.

What happens after you press 'save'?

In your last picture you have nothing in the password field, that should be populated. And why does the hidden smtp server just have yahoo, that's not a host name, and I bet it still doesn't have a proper password.
