The milter specification doesn't list which values ("macros", in sendmail
parlance) are passed down. It's entirely up to the MTA and the filter to
negotiate that.
Recent versions of the milter protocol include a mechanism by which the filter
can ask for specific ones, if the MTA supports that request. The MTA just
needs to know what to return in each case.
