I have an email account through AT&T/Yahoo and last night I noticed that I could no longer download my mail into Thunderbird! I was going crazy trying to figure out why and this morning I found out.

Why they did not send this message out ahead of time is beyond me but here it is:

We're making some security improvements to your AT&T Yahoo! service. These changes will affect members who send or receive email from a desktop or mobile client program, such as Microsoft Outlook, Microsoft Outlook Express, Eudora, Apple Mail, or Thunderbird.

  • Open your email client program.
  • Locate the email account settings for your particular client.
  • Change the POP server to pop.att.yahoo.com.
  • Change the SMTP server to smtp.att.yahoo.com.
  • Check the option labeled Use an encrypted connection (SSL) and change the SMTP port to 465.
  • Check the option labeled Use an encrypted connection (SSL) and change the POP3 port to 995.
  • Confirm the above settings then click OK.

That's about it. Good customer service would have been sending out an email notification a week or two in advance of this change. I have to wonder how many tech people like me were getting phone calls from relatives to fix their email.
