Email Account unable to send message since hack

Hi BT,

A customer of mine is with BT and there email account was used as a SPAM source.

I have now corrected this problem but they are still unable to send messages. I think there account is still blocked?

I phoned BT today but the issues has still not been sorted. Reference: ******

The account in question is

When we go to send an email we get a bounce back stating: -

Your message couldn't be delivered because you weren't recognized as a valid sender. The most common reason for this is that your email address is suspected of sending spam and it's no longer allowed to send messages outside of your organization. Contact your email admin for assistance.

Please can this be resolved ASAP.

Hey Rmculver,


The fastest way to sort this would be to contact the livechat team using the link below:

It most definitely looks like the account has been restricted and by contacting technical help, they'll be able to get your issue to the second line support team during your chat and get that restriction lifted. 


Thank you, Bobby
