Some spammers are able to get through by using a mailhost which I do not control (it is a xecondary mx for my domain), so I want to have lists of "Received" headers and IP addresses which send me nothing but spam and have courier-maildrop use them. Is this possible?

You could use something like this:

foreach ( /^Received:.*/ ) { COUNT=$COUNT+1 if ($COUNT == 2) { ( $MATCH =~ /\[![0-9\.]+/ ) xfilter "reformail -A 'MX IP: $MATCH2'" } }

This example extracts the IP-address of the second `received' line - usually your backup mx.
