Unable to send emails, "Failure sending message: email address not valid"

[rbickley]

I am receiving all emails to this slave email with no issues however I have been unable to reply to or send any emails for 3 weeks on all devices, when using TPG post office I am getting the error message "Failure sending message: Email address not valid. Please use an email address which looks like user@example.com" when attempting to reply to valid addresses.

I have changed my password with no improvement. Are you able to assist further?

Thanks in advance.

Thanks for your help David. Unfortunately I missed the call the next day and have been unable to get back in contact since. Is there a number I can call?
