As Heiko said: Please don't obfuscate. That makes it hard to diagnose
your problem without having to spend quality time filling in the
missing bits.

You wont lose any security in leaving email headers unmolested, unless
you are doing it as a courtesy when quoting information about someone
else's email. Even then, it is just a courtesy and not a security
enhancement.

However: we will probably need your selector (unless it really is
s=selector) but never diclose your private key, for obvious reasons.
