Are you perhaps refering to client software, using the 'is-spam' header
for separating spam from ham? In this case, it is possible the
untrustworthy headers will be used instead of the ones added by your own
spamfilter. This might be solvable by prepending either your own or the
third party headers with a known prefix.
The second case is referring to a redirect. According to the SA
documentation, a redirect should not obliterate the existing SA headers
(<http://wiki.apache.org/spamassassin/ResendingMailWithHeaders>).
It appears Amavis is violating the SA design.
