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.
TrendNet Model TV-IP110W and TV-IP410WN.

I'm experiencing the exact same problem. I use Panasonic IP cameras in the same manner. They are spread across two separate ATT U-Verse accounts, and all cameras on both accounts stopped sending e-mails at the same time. All other functions of the accounts still work fine, and the cameras are still accessible and otherwise working fine. It is definitely related directly to using port 587.

You're welcome. I also sent a PM to tech support, if I get a resolution and it's not reported here I will relay it.

If you just started having trouble with your email client, it is most likely related to a change that took place on December 11, 2013. Please use this article to update your email settings.

Client based email applications will require SSL to get the emails delivered.
I believe you might have to replace the H/W.

Thanks. Yes, that's probably what's going on, but those instructions make no specific mention of port 587. All of the settings shown are what I have been using for a few years now for everything else (i.e. other software e-mail clients), all with SSL.
Port 587 is what all of us have been using with older hardware that didn't support SSL. Hundreds of dollars worth of hardware, which is probably now useless. Thanks ATT. Is it really that big of a deal to maintain one non-SSL server?
Another work-around, of course, is to use a third-party e-mail provider with their own SMTP servers that do not require SSL, they're out there, but of course that is additional expense.

As of December 11, 2013 the use of Non-SSL settings on client mail stopped sending and receiving. This includes the use of SSL override port 587. AT&T began using SSL about 5 years ago but not all of our customers had updated their client settings.
AT&T Yahoo mail servers will no longer allow to send or receive email if email settings have not been updated to the current client email settings:
• Incoming mail port #: 995, secure connection (SSL) checked
• Outgoing mail port #: 465, secure connection (SSL) checked

I am unable to access my internal POSTFIX service (with STARTTLS) via port 587, probably because of an ISP level port block. I have setup a port forward in my router from external port 4587 to internal port 587 and this works fine as a workaround for accessing the server remotely, but when a portable email device such as my phone is connected to my home WI-FI, I then would have to manually change the port back to 587 or reconfigure POSTFIX to listen on a different port completely all the time. Neither solution is ideal and I was wondering if I could just get the port 587 block lifted on my account so that I don't have to jump through hoops just to access my own computers in my own home.

Hate to say it, but we don't have that ability (by we I mean customer care teams, or customer service). And I have never heard of anyone getting that port unblocked. So you will have to change the port on your side..
