When I try to get an existing mailbox set up, the message is that the address is "configuration found on ISP Database. anything I do after that results in a "Configuration could not be verified-is the the user name or password wrong?" This is the user name and password I use to get into the mailboxes in the mail section on earthlink site. I got one to download that is @earthlink.net, but the other three are on @mindspring.com. They were all working fine for years until my computer crashed last month, pretty well knocking out my entire mailing system and other online links with Firefox.
