Can't find SMTP address

  • Answered
On October 14 AT&T shut down the SMTP server ( which I had been using with my Thunderbird email client for many years. They made all AT&T customers (I use AT&T DSL) switch to SMTP By calling AT&T tech. support I was able to have them change my Thunderbird SMTP address to and it worked for my email address.

Of course all my incoming (POP3) emails are retrieved by Thunderbird.

However, I have six (6) "non" AT&T email addresses. Five with and one with a GoDaddy ( Changing the SMTP setting to didn't work. The server gave me an error message.

After three days and as many phone calls to AT&T tech the support the tech switched me to a supervisor (because he didn't know how to solve my problem) and the supervisor, after telling me that AT&T did not support Thunderbird admitted it was not a Thunderbird problem but the "problem" was that AT&T SMTP servers would no longer accept any From: emails that were not an email.

Both localnet and GoDaddy email SMTP servers will only allow connection via their web mail. So I have no SMTP server address to put into my Thunderbird for those email addresses.

Can you help (please) or am I going to have to "bow" to AT&T restrictions and cancel all my "non" email accounts and create addresses or after many, many years of using Thunderbird, start using those stupid web mail facilities.

Hello Robert, Thank you for your question on setting up SMTP settings for your Thunderbird. I hope I followed what you are saying. Are you saying that when using Thunderbird to connect to your GoDaddy and localnet email, forces you to use their outbound settings, but since they have changed, they do not allow any emails to route through their SMTP servers? If the ISP is forcing this, then you may not have a choice if you insist on still using the Thunderbird client. If you use a webmail client (which logs into the mail server via a browser interface) you will not have that issue. Of course you would need to set that up and it may have different features than what you have in Thunderbird. Google is also an option (gmail) as you can set up a gmail account to function as a POP3 or IMAP client. Again, you would be logging in via browser so your ISP would not be involved. Google has nice tools and features as well, so you may want to consider one of these options. Kindest Regards, Scott M
