BT Yahoo Email Security Upgrade (Error 553)

[link to this post]
Copy of post detailing changes to BT Yahoo email service

We’re re-starting the changes we’re making to how users send email using BT’s SMTP servers today. We’ll be gradually rolling these out to all our customers over the next few weeks.

These changes are intended to help prevent identity fraud and spam while also protecting you from 'spoofing' - when people use alternate addresses to disguise an email's real sender, possibly to commit fraud.

If you use our SMTP servers to send email where the From address does not match your BT Yahoo! Email address then you will need to verify that From address on that account using a simple on-line form. If you try and send from a non verified email address you’ll get an Error 553 message.

To avoid this you can find instructions on how to verify your email addresses here

We won’t ask you for any personal details but you will need to log in to your account to make the needed changes.

Note: To send from your sub-accounts while using your primary email address you will need to verify your sub-accounts on your primary account.

We originally introduced these changes back in March but the changes affected a significantly larger number of people than we expected so we placed them on hold until we could communicate with all the affected users. We’ve now finished emailing everyone affected by this. In addition anyone getting an Error 553 will also receive an email with instructions on how to verify.

We hope this doesn't cause you any inconvenience and appreciate your co-operation.
