Why is there trouble sending email when AVG VPN connected

Hello Bill,

We are sorry to know this.
We would request you to refer this article and make some changes as described in the reference file.
Thank you.

I like several other VPN users have problems sending emails, they appear to go nowhere except my sent box when VPN connected.
I have performed all the recommended settings but the problem persists on all my tablets, laptops and my desktop. My email service provider help desk has also tried looking at the settings but has also not helped the problem. I have now turned off the VPN!

I have performed all the suggested setting reviews! No change I can only send emails by turning AVG VPN off!
