which is the standard MailScanner version of the SpamAssassin header. It is
the list of rules that "hit" as given by SpamAssassin.

That is the really noisy verbose report that is useful for testing but not
much else. MailScanner never produces this. After all, do your users really
want this at the top of every message they receive? I doubt it.

Because it uses the "brief and to the point" version of the report, rather
than the (overly) verbose version.

SpamAssassin can be configured to produce pretty much the same report as
MailScanner produces. The "spamassassin -t" output is only intended for
MailScanner thanks transtec Computers for their support
