I am using pop3 for connecting mail server box. I am using following code for this:

using (Pop3 Inbox = new Pop3())
{
     Inbox.Connect(host);
     Inbox.Login(username, password); 
}

I am getting error on login. Following is the StackTrace of exception:

Answer 1

This error is returned by your server.

Most likely you are using incorrect credentials. Please make sure those are correct. You can try using full email address as login.

Please turn on logging:
