Cory,

(as Daniel Luttermann and Clifton Royston already answered most of your
questions, I'll be short)

Spam headers shouldn't be missing even when spam result comes from a cache.

To turn off spam cache:
  $spam_check_negative_ttl = 0; # time to cache contents as not spam
  $spam_check_positive_ttl = 0; # time to cache contents as spam

You forgot to add SA rules to assess header as provided by dspam.

Search for DSPAM_SPAM in RELEASE_NOTES for an example.

I agree the do_quarantine should be modified to provide dpam header
in the quarantined message.
