If this is an example of the civility you use when trying to resolve the issue, I'm not surprised that your requests have gone unanswered.

And you think that your communication would be completely unmonitored otherwise?  Did you install the hardwire between you and your destination yourself, or something?

Which removes one concern from not smarthosting your mail - the ability to track down and/or otherwise control that portion of the delivery cycle.

I block somewhere around 60% of my incoming connections because they are spam.  They're on blocking lists, both off-site (SORBS, etc) and my own.  I can guarantee that they're spam.  How?  They're to addresses which were never meant to accept incoming mail.  My logs confirm it.  As far as I can tell, I've blocked 2 legitimate messages in the past three years based upon these criteria.  Obviously, YMMV.  At one point I was blocking over 10,000 messages a day from dynamic IPs on cable modems.  Their ranges weren't otherwise listed, and it took their providers in excess of three weeks to address the problem.

But one thing I don't understand: why do you feel you have any expectation to absolute privacy via email, especially when you're also demanding 100% deliverability?
