I'm aware of the fact that amavisd is run before the policy daemon if
configured as a smtpd_proxy_filter. This is why I asked "Is there any
way to flag anything so amavisd skips it's checks?"

The only way I found so far is to set an extra header in postfix via
PREPEND. This extra header can be evaluted by spamassassin setting a
very low score. Unfortunatly this doesn't cover virus or bad header checks.

amavisd's bypass and lovers maps are for recipients, only.

Any idea how amavisd can be configured to skip checks if an extra header
is set?
