My registration for Yahoo mail has been approved. But internet tells me they have no such address. why?

Question

I also could not access my password. why not?

Answer 1

What u mean 'Internet Tells'.
Do u mean that there is no address 'mail.yahoo.com' or '[e-mail]'

If the former is the problem,it is either with ur ISP,firewall.
For the latter,There may be chances that u had entered an id mismatch with what you think.
