Good idea. :)  Here are the SpamBouncer headers:

X-SBClass:
X-SBNote:
X-SBPass:
X-SBRule:
X-SBScore:
X-SBStop:
X-SpamBouncer:

The X-SpamBouncer header appears first, and gives the version number
and release date of the SpamBouncer release the individual is running.

The X-SBNote/X-SBPass/X-SBRule/X-SBStop headers come next.  None of 
these headers always appear, and most can appear more than once.  An 
X-SBNote notes something of interest, but doesn't affect the email's
score.  X-SBRule refers to any filter that affects the score, either
positively or negatively.  X-SBPass refers to a whitelist filter --
anything with one of these is delivered without further filtering.
X-SBStop refers to a "show-stopper" blacklist filter -- anything 
with one of these is stuck in the VIRUSFOLDER or SPAMFOLDER without
further ado.  (X-SBStop tags are used only for viruses or "dangerous
content" -- stuff that could be a virus or trojan.)

X-SBScore: shows the email's final score, and also displays the 
"SpamLevel" and "BlockLevel" settings for this user -- the scores
at which email is classified as definitely spam, and as suspicious/
blockable.  Finally, X-SBClass shows the final classification of 
the email -- Virus, Spam, Blocked, Bulk (legitimate bulk), Admin
(postmaster/MAILER-DAEMON/etc.) or OK.

Depending on a user's configuration, SpamBouncer may only add a
few headers, or may add a *bunch* of headers, but they'll all
be one of those six types.
