@mjs-warlord Thanks for confirming that, it's one of the things that can cause this type of error.
I'll send you a private message so you can get in touch with the moderation team and we'll be happy to help.
no i am not using a vpn ...... its one of the first things they ask .... i have to copy all unsendable emails into a gmail address so i can send them but that NOT an exceptable work around
There's your answer.
Stop using BTinternet email address and use Gmail instead.
BT will NOT investigate this common issue properly, they keep thinking it's a new fault every time.
You and others are banging your head against a brick wall, use Gmail.
It is a very state of affairs when somebody like you has to tell forum users to dump bt .... no insult to you or your hard work g nite
