This method will connect to SMTP server specified in
Hostname property. If Hostname property contains more
than one line, it will connect to the server that is in the
first line of Hostname property value.
When connection is initiated, Connecting
event will fire and it will contain hostname of SMTP server
where wodSmtp is trying to connect.
There is no need to issue Connect method
manually, because if you use SendMessage method, it will do
the job for you.
