sbcglobal.net address is no longer receiving mail
My yahoo.com email address is still properly receiving email, but my sbcglobal.net address does not seem to be associated with the yahoo account anymore. I had been receiving emails at the sbc address up until 12/29/17, but have not received on at that address since. I've also tried logging into the sbc account from the start.att.net account, but it just bounces me to my yahoo account.
I've tried sending email to both the yahoo and sbcglobal email addresses from a third address. The yahoo addressed emails are coming through, but the sbcglobal addressed emails are not.
