Pop3Client.Authenticate(String, String) Method

Authenticates a user towards the POP server using Auto.
If this authentication fails but you are sure that the username and password is correct, it might be that that the POP3 server is wrongly telling the client it supports Apop. You should try using Authenticate while passing UsernameAndPassword to the method.
