Determines if APOP authentication is supported.

A boolean value.  

object.EnableAPOP [= value]

The EnableAPOP Property syntax has these parts:

EnableAPOP property determines if server will respond to APOP command. By default, it is set to False and server ignores this command, since you must handle authentication in Connected event for this command to work. If you enable it, make sure you know user's password, and call TestAPOP method inside Connected event to test if password is valid.

In APOP command, password is never sent by the client, you must know the password locally.
