I just set up an email account for Pro-Mobile Ltd. That address is: promobilelightsandsound@yahoo.com. When I send an email to this address I get a "failure to deliver" email stating that the above address does not exist. Contained in these notices is a link to the email address yahoo@product.communications.yahoo.com. When I click on this link I get a Yahoo mail "compose" page addressed to the above Yahoo email address. When I explain my problem and hit send I get another "failure to deliver" email stating that the above Yahoo address does not exist. All of these messages are being sent to and received by promobilelightsandsound@yahoo.com. I have sent this message using this platform as the Yahoo email address: yahoo@product.comunications.yahoo.com apparently does not exist. So far I have received 1 response asking me to provide a Dm and "screen shot on Twitter. I do not have the foggiest idea what these are and as I have never used Twitter and do not know how I can not comply with this request. Please help.
