/**
*The POP3ServerException class represents a server response
*error in the POP3 implementation of the Messaging Access SDK.
*<p>The POP3ServerException class handles server response errors.
*A POP3ServerException is thrown only from the error
*callback on the response sink. The interface definition for
*IPOP3Sink states that a POP3 server exception can be thrown,
*but it is up to the developer to determine whether or not
*the implementation of the error callback will throw this
*exception. As a default, the POP3Sink class throws an exception whenever
*the error callback is called.
*<p>This exception is caused when the server sends an
*error saying that some part of the operation failed or is not
*supported. This can happen even when all relevant code executes
*properly.
