Internal IP address obfuscation?

In procmail, you'll probably end up with a filtering pipe to sed
or something similar.  Are these IP addresses only in Received:
headers?  Or in some other header?

        
        :0 fwh
        * ^Received:.*\<172\.16\.1\.
        | sed 's/172\.16\.1\.[0-9]*/x.x.x.x/g'

is one example that should work.
