How can BT's "content policy" blocking of email sending be switched off? It is completely inappropriate and unacceptable.
Phishing and ERR Code 553 started on my system when I turned on my AVG VPN, even though I was not using their browser to access BT Internet Emails. Turning it off, as advised in a previous post immediately fixed the problem.
Turning it off also revealed something I didn't know. By turning on AVG secure VPN browsing, it is the internet connection itself which is connected to the VPN, so any browser then goes through the VPN.
I discovered this because by simply turning off my AVG VPN connection, my BT box disconnected itself from my PC!!!
