NOTE: This method is called only if you
implemented IwodSmtpClientNotify interface in your
application, and wodSmtp1.Notification
property has received reference to
instance of your implementation.
Disconnected notification method is called when wodSmtp
disconnects from the server, either due to using Disconnect method,
or because server closed the connection. If error occurred,
ErrorCode and ErrorText arguments will provide information
about the error.
Disconnected method can be called also as a result of
calling Connect and SendMessage
methods - if disconnection occurred because server was
unavailable, authentication failed etc...
