No X email

This is not a big deal because i never use the account but it would be nice to have my cable modem mail address in working order.
Using Jaguar's (10.2.3?, it's updated) email function (the stamp), i am getting message that password has been rejected. Just to make sure i had the right one, i changed it. The new password works fine on a a free internet POP email service

i can access it fine, new password and all.
The only new wrinkle i see is that Jag asks for a user name. I have no idea what a user name is. I have an address and a password, the mail severs, etc. I dont understand what a user name is and don't know if it's important.
Thanks

I think the Mail.app is asking you to authenticate yourself to the POP server. When you set up the account in Mail there was an option to save the password to the Keychain, did you do it? I think that's what's happening here. The user ID it's asking for is the one for your email account.

I set the email password.  I dont know about a keychain.

The Keychain is an application which stores your internet, application or other passwords. You can open it up and see what's there in /Applications/Utilities/Keychain Access

Two things maybe happening, either you need to authenticate yourself to your ISP's POP server using your email ID and password or you need to authenticate yourself to the Keychain app using your OS X shortname and password.
