I was sending emails this morning , a I can't send anything due to Error Code 553 showing up.
I have sent myself a test message with just the heading, but that does not work .
Emails are still coming in, but I can't respond to them.
I can send from my other email @icloud,of which I have there is no problem
I have turned off the Home Hub for an hour twice and this made no difference at all.
Your help to resolving this hugely frustrating issue would be appreciated, but may I ask one thing ?
I am a computer novice , if you are going to offer up a technical explanation, please respond with the simplest version
I would add that I go into my BT email home page via Chrome and then log via the BT email log in.
I hope you can rectify this soon. Many Thanks
