BTW if this is a SMTP error i can't do nothing. You have to treat this email as valid and send a mail to the user to validate the mail. This library can't validate an email at 100%, it should be used in addition to the send of an activitation email for exemple.

func main() {
    err := checkmail.ValidateHost("validuser@gmail.com")
    if err == nil {
        // user ok , no need to send an activation email 
     }
     if err != nil {
       // validation email
     }
}

should use certain smtp setting to make this library works?
