Is there an equivalent X-Amavis-AV-Status header for AM.PENPAL

Hi,

Today a lot of my users have been receiving a email with a dynamic Word attachment which contains a macro.

I've tweaked the score I had for (Heuristics\.)?OLE2\.ContainsMacros from 4 to 10 in virus_name_to_spam_score_maps which is blocking the messages for now. 

@virus_name_to_spam_score_maps =
 (
  new_RE (
   ...
   [ qr'^(Heuristics\.)?OLE2\.ContainsMacros' => 10.0 ],
   ...
  )
 );

However I know from past experience that when I ramp up this score I get complains from end users they they've not received a email "they always used to get". I''m sure we all agree that sending or receiving emails with macros enabled attachments is a no no, but unfortunately in the real work daft things happen.

During further research I found this http://lists.amavis.org/pipermail/amavis-users/2011-October/000934.html which has allowed me to utilise Amavis / ClamAVs detection of the macro in SpamAssassion

header __SCS_AV_MACRO X-Amavis-AV-Status =~ m{\bAV:(Heuristics\.)?OLE2\.ContainsMacros}i

What I was wondering is there a way I can pass Amavis AM.PENPAL status to spamassassin? The long term goal being a meta rule in spamassassin which checks if you're a PENPAL and a Macro sender then knock a few points off (or more likely if you're a Macro sender and not a PENPAL then add a load of points on!)

Any thoughts gratefully received.

Regards

Steve
