Hopefully one of you technical gurus on here might be able to tell me if I need to be concerned about this.
For years I was with Talk Talk and operated from a TalkTalk email address. However, over the last year I have been replacing this TalkTalk email address with a GMail one, and finally last month I switched my internet provider to BT, no longer concerned that I had any important stuff connected to the TalkTalk email.
Now, I do still receive the occasional email from that TalkTalk address, mainly shopping websites with offers I have signed up to in the past. However today when I logged in I had 4 email undeliverable failures in my TalkTalk inbox. The 2 files attached to each seem to make it clear that someone is sending emails using my TalkTalk email address, but that someone isn't me and where the recipient doesn't exist I am getting the bounce back. Should I be concerned or not?
This is the contents of one of the attachments - with my email address highlighted and anonymised.

As I said, I haven't got a clue on this stuff, so don't know whether to pursue or ignore
Cheers
