You can start your data-acl with something like
accept condition = ${if and {\
{def:h_X-Scan-Signature:}\
{eq {${hmac{md5}\
{iWillNotTellYou}\
{$body_linecount}}}\
{$h_X-Scan-Signature:}\
}\
}\
{1}{0}}
logwrite = correct X-Scan-Signature, size=$message_size
and end it with
warn message = X-Scan-Signature: ${hmac{md5}{iWillNotTellYou}\
{$body_linecount}}
accept
That frame would prevent running any tests between those statements, if
the message has been processed by your servers before AND nothing has
changed the linecount. If some Mailinglist appends a footer, you'll have
to either accept double-scanning in that particular case or do something
more complicated.
