Send method allows you to send arbitrary string
expression to connected user at any time. However, be
careful not to violate SMTP protocol specifications, so use
this method only if you know what you're doing. Mostly
this method is here for implementing new commands, and
changing defined ones, in case there's need for it.
Theoretically, using Command
event and Send method you can completely rearrange and
change behavior of wodSmtpServer to make it work as
something else, like Pop3 server. But, please, do not
try this in real life. Or, at least, don't ask us to
support it...
