Email verifier error


New Member
Hello everyone,

I am getting error #103 when I test my own personal email address.

I have contacted my ISP and my port 25 is open.

But when I change my IP address and test it, it works and says email is valid.

I tired again to test my email and it says timeout. Then I disconnected my vpn and changed my IP again and it works. Also if I wait a few minutes to run the test without disconnecting my vpn it works.

I would like to know how I can fix this error
