While I applaud your initiative, particularly if this is an exercise to
teach yourself about java, dns, and smtp, I'd have to ask: why are you
writing such a thing from scratch? There are literally thousands of them
out there already that have been tested, debugged, and refined. You
might even find answers to your question by reading some of that code.
