missing X-Amavis-OS-Fingerprint header

[Jose Guevarra]

Hi,

i'm using amavisd-new-2.7.0 with p0f 2.0.8-r2 which resides on a 
different server than amavisd.

my config file has these entries

$os_fingerprint_method => 'p0f:my.mail.server.com:2345';

%allowed_added_header_fields = (
   lc('X-Virus-Scanned')         => 1,
   lc('X-Amavis-OS-Fingerprint') => 1,
   lc('Authentication-Results')  => 1,
   lc('X-Spam-Status')           => 1,
   lc('X-Spam-Level')            => 1,
   lc('X-Spam-Score')            => 1,
   lc('X-Spam-Report')           => 1,
   lc('DKIM-Signature')          => 1,
   lc('X-Spam-Checker-Version')  => 0,
);

When recieving mail the  X-Amavis-OS-Fingerprint header doesn't seem to 
show up.


When setting the log level to 4 i see these log entries

(11929-01) Fingerprint query: [209.85.160.53]:53362 NQsD2sFW8LaU 
(p0f-analyzer) p0f:my.mail.server.com:2345
(11929-01) Fingerprint collect: max_wait=0.016, [209.85.160.54]:53362 
NQsD2sFW8LaU ... =>

can anyone possibly hint as to why the headers are not showing up or 
where else to start troublshooting this?

Thanks.
