Last April I created email alias for several web domains that I own. Through my web host, I established a forwarding mechanism so that any email to those aliases is sent to my Verizon email account. This worked for eight months, until this morning. There's no problem on the web host's end, and I even added a Gmail account to receive the messages sent to the alias email addresses. That works fine. But Verizon is no longer accepting emails from my aliases. How can I make Verizon begin accepting emails from my aliases?
