postfix, amavis relay filtering

Hello,

I set up a box with the following tutorial -> http://www.howtoforge.com/virtual_postfix_mysql_quota_courier

When I configure some relay domains, it seems the tagged SPAM messages are forwarded without a tagged subject and without spam header information.

What do I have to do to have relay mails also filtered? I'm using the standard configuration for amavis and postfix you can find in the tutorial.

 

I think the relaying is done before amavisd is called...

 

Hm, and how this can be solved?

 

I don't know if there's a solution.
