Sebastian, 

try the recent released amavisd-new-20030616-p8 . It includes an updated 
version of amavis-milter with such features and less requirements - and 
the code is way better. 
As points out amavisd-new-20030616-p8 RELEASE_NOTES :  

helper-progs/amavis-milter.c (sendmail) enhancement based on work
  by Stephane Lentz: 

  * the name of a temporary directory is derived from the sendmail queue ID,
    making it easier to match sendmail and amavisd-new log entries;
    the queue ID is also a part of the quarantine file name;

  * a phantom 'Received:' header field is prepended on the temporary file
    to preserve the information on the original SMTP client IP address,
    host name and queue ID. This trace header field does not propagate to
    recipients (is not inserted into the original message), but is available
    in the quarantined messages and is visible to SpamAssassin.
    Adding a milter macro {b} on ENVFROM is advised to preserve the MTA
    timestamp in the log, although not mandatory (falls back to current time):

      define(`confMILTER_MACROS_ENVFROM',
              confMILTER_MACROS_ENVFROM``, {b}'')dnl

  If the new amavis-milter.c gives you trouble, switch the soft link to the
  previous version in the same directory. Keeping macro {b} does not hurt.

Thanks to Mark, Milter users now will be able to track infected/spammers machines 
easily.
