The following is my patch to tmda-rfilter to extract the address
extension from RECIPIENT_HEADER, rather than the EXT or EXTENSION
environment variables, if RECIPIENT_HEADER is set and the named header
exists. This makes it easy to use tmda in situations where EXT isn't
set (eg, behind fetchmail).
It applies cleanly to 0.69.
Comments welcome.
