[Mimedefang] Previous relay information

[Mark van Proctor]

Hi all,
 
After a fair bit of effort I have managed to implement graylisting /
whitelisting using mimedefang (with sqlite) - it works fantastically so I'm
very proud. *blush*
 
A couple of spam, however, are getting through by sending to our secondary
mail server, which we have no control over and which is then forwarding the
emails to us (in an smtp compliant manner... respecting out TEMPFAILs and
sending again when it can...).
 
Has anyone implemented some form of parsing of the received headers to
determine who the previous relay was? When is the earliest time that these
headers are available? filter_begin? Are these easily accessible through
mimedefang's variables or will we need to build some kind of script that
will parse the actual mail files?
 
Any help / thoughts / suggestions are much appreciated!!
 
Mark
