I am a TalkTalk Fibre customer.
When I try and send a onetel.com email via the app (https://apps.talktalk.co.uk/appsuite/), I receive the error message:
An error occurred inside the server which prevented it from fulfilling the request.
I am also using Thunderbird and have an email account from onetel.com.
Suddenly, if I try and send emails from the onetel address I am getting an error message:
Sending of the message failed.
An error occurred while sending mail. The mail server responded: Reject for policy reason. Please check the message and try again.
If I send an email via another address, such as gmail the email is delivered. Hence, it seems a talktalk issue. I use:
smtp.talktalk.net
Port 587
STARTTLS
Normal password
I cannot sent emails from an onetel email address to any gmail addresses. I can sent to the same onetel email address.
Why are onetel emails being blocked?
