In reply to Toerag:
As far as I'm aware, the UKC messaging has always just set up the option for you and the other user to converse directly by email and you never could have messaged anyone without sharing your own email address.
It always used to do that by utilising the "reply to" field within email. So if I sent you a message, the email to you would come from [email protected], but the "reply to" field on that email would be set to my email address so that if you hit "reply" within your email client it would email me directly and cut UKC out of the loop entirely.
If your reply has actually gone to the UKC messaging address, I would expect that to return the error you got because your reply should have gone to the user's own email address. The two options I'd suspect would be:
- The setting of the "reply to" field has gone wrong, either because UKC made a tweak that accidentally broke it or because a provider somewhere along the chain has deliberately blocked it
- Your email client doesn't obey the "reply to" field. You could try accessing by a different route.
I've attached an image of how the process used to look within the standard Android Gmail app. So you can see that the email came to my Hotmail address from UKC, but my replies would go to the user's Gmail address.
