SMTP port 587 just stopped sending emails
I've been sending emails via smtp.att.yahoo.com port 587; non-SSL for years now using an sbcglobal account. It stopped working in past couple of days.
Is this an incident that needs resolved within AT&T? Or a policy change?
I have two security cameras that do not have the ability to send via SSL, and the feeds from the event (motion detected) have stopped being emailed. I would prefer to get these working again. As opposed to buying new hardware.
