OpenPop.Net : Fetches old unread emails from the mail server in ASP.Net

It displays only unread emails, hence there is nothing we can do for it, it will fetched whatever it finds unread. You need to check date and process in your code by yourself

Try with a different account, I would suggest as if your account is sending old emails there's nothing which can be done

Thank You Sir,

I've found the solution; i just need to configure the Gmail settings and the problem is solved.
