BT Yahoo! Mail - setting up SMTP Authentication

What is SMTP Authentication, and why do I need to ensure it is switched on?

As part of a worldwide initiative aimed at reducing junk email (spam), all email providers are switching to what is known as 'SMTP authentication'. SMTP stands for Simple Mail Transfer Protocol, which enables the sending of email. Authentication is a method of identifying the origin of emails that stops emails being sent anonymously.

Most nuisance emails (spam) are sent from people on unauthenticated email. By removing the ability to send emails without authentication, spam should be substantially reduced.

How do I switch on SMTP authentication?

It's simple. 'SMTP authentication' is usually switched on by ticking a box called 'My server requires authentication' in your email program settings (see below).

Please do this for all the BT Yahoo! email addresses that you and your family use.

  • If you are using Microsoft Outlook Express or Microsoft Outlook on a PC, this can be done automatically for you - just click on the button below, then click 'Yes' when asked if you want to install and run the program. This will switch on SMTP authentication in your email program on this computer for all your (or your family's) BT Yahoo! email addresses.



  • If you're using another email program, OR you're using an Apple Mac, OR you prefer to do this manually, please click here to see how to switch on SMTP Authentication.
