I have a "user@yahoo.es" address. People send me mails to the "user@yahoo.com" alternative all the time. Since it is another dominium I never get those messages.

I couldn't create my address ending yahoo.com, because "I already have the account". Since nobody will ever be allowed to use the same address at the "yahoo.com" dominium, I would like to have the possibility to get those mails at my own "yahoo.com" address.
