This message seems suspicious...

[CliffA1905]

I will email myself with reminders, over the last few days I have a pink box at the top of all my emails saying this message seems suspicious, when I click into the take action box, it directs me to the help page with a new mesage saying this page was not found.  I have tried updating my details, however this has not made any changes.

As long as these emails are coming through to your inbox then you might not be able to so anything with this as it is probably something Yahoo are flagging up due to the emails having the same sender and recipient email address.
