Well if you are considering the plain-text of an encrypted mail, it doesn't much matter whether port 25 is intercepted by whatever governmental agency, or relayed through however many servers with questionable operators.
And quite frankly, he was right - that's the only way to do it right.
Oh I agree. My point to the original poster was that supposed security of port 25 communications was not a good reason to avoid using relays on the way. If you want security of you communications a good first step is PGP (et al.). (Note that this does still leak To:/From:/Subject: lines, but they be read via wire-tap just as they can be read via intercept at a relay). Alex
