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.

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).
