So, to recap, if I set my postfix server to send direct via DNS, it may, or masy not, be logged by my ISP, depending on their nosiness. For incoming mail, I use Freeparking (http://www.freeparking.co.uk/) to redirect to my own DNS server. Does this bypass my ISP or not? Many Thanks John Per Jessen wrote:

And the funny thing is that if I wanted to contact my nogoodnick buddies, I would choose to use other than port 25. Maybe their evil smtp daemon is listening on port 666 (evil, don't ya know). Just about any e-mail client lets you select the port. All this with standard off-the-shelf software.
But of course - however, the point is really that if someone wants to spy on you and your internet-traffic, there's very little that'll stop them. If instead it's mostly about avoiding leaving an immediate trace, security by obscurity does work quite well.
