Hello there,

   due to too many smtp-auth attempts, we decided to only allow the authentication from certain countries in Asia. But some of our users prefer to use Gmail Web. They set the Gmail to greps emaisl via pop3, And this behaviors became a client is using pop3 to login from the US.

   I just want to check if it's possible to block the authentication from the US but allow the access from google domain?

   Thank you.
