Describes the authentication method to use when authenticating towards a POP3 server.
|UsernameAndPassword|| Authenticate using the UsernameAndPassword method.|
This will pass the username and password to the server in cleartext.
Apop is more secure but might not be supported on a server.
This method is not recommended. Use Auto instead.
If SSL is used, there is no loss of security by using this authentication method.
|Apop|| Authenticate using the Authenticated Post Office Protocol method, which is more secure then UsernameAndPassword since it is a request-response protocol where server checks if the client knows a shared secret, which is the password, without the password itself being transmitted.|
This authentication method uses MD5 under its hood.
This authentication method is not supported by many servers.
Choose this option if you want maximum security.
|Auto|| This is the recomended method to authenticate with.|
If Apop is supported by the server, Apop is used for authentication.
If Apop is not supported, Auto will fall back to UsernameAndPassword authentication.
|CramMd5|| Logs in the the POP3 server using CRAM-MD5 authentication scheme.|
This in essence uses the MD5 hashing algorithm on the user password and a server challenge.
