Note that AT&T / Yahoo intendes to require that your e-mail client (e.g. Outlook, Thunderbird) use an SSL connection (vs. a non-secure connection) within the next 30 days.
Please review your settings and make sure they match the ones in this page:
Or, if you'd rather, AT&T has an automated tool to set up correctly, if your system meets certain criteria. More info here:

This is a bummer. I have configured Thunderbird to use SSL on 465 and it works ok with one exception:It is apparent that SSL login authentication for outbound.att.net requires that your email address in the outgoing e-mail match the AT&T account login address (email@example.com for DSL accounts set up in the days when DSL was provided by SW Bell in Kansas City)
This is a problem when I try to send text messages to a users phone via the e-mail address for the cellular carrier. In the case of Verizon wireless customers it is firstname.lastname@example.org. In the case of AT&T wireless customers it is email@example.com.
This still works from Thunderbird with SSL connection to outbound.att.net but forces me to change my e-mail address from my firstname.lastname@example.org to my AT&T e-mail address.
Why is this a problem you ask. Because I want the "from" address of the text message the recipient receives to be email@example.com so that when they "reply" to the e-mail delivered as a text message to their phone, their reply is sent to firstname.lastname@example.org so that I receive their reply as a text message to my phone and not as an e-mail to my AT&T(swbell) e-mail account.
That worked perfectly when I was using smtp on port 25 to mail.swbell.net. It no longer works with SSL to outbound.att.net because my from address (email@example.com) does not match my DSL account login (firstname.lastname@example.org) required for the SSL connection to outbound.att.net
I'm confident that this is an attempt to make spam e-mails harder to send from AT&T email customers (whether from the customer or from a spam-bot infecting their computer). This does interfere with legitimate (and useful) e-mail addresses (e.g. email@example.com) or your_name@your_work-email.com.
I tried setting my firstname.lastname@example.org account to email@example.com with the return address specified as firstname.lastname@example.org but that did not work as the "reply" from the recipient's cell phone went as e-mail to email@example.com.
Sorry for being wordy but i'm just venting my frustration with this change.

Does Thunderbird not allow you to set a "Reply To" address different from your "From" address?
If one is present in your SMTP headers, the mail client is supposed to use it instead of the "From" address to send replies to.
