As I explained in a different response, there is no "this table"
concept outside the low-level (pcre, hash, etc.) table itself. At
higher levels, there is a lookup result without source attribution.
Considering Postfix's drive to economy of mechanisms, a "this table"
concept at higher levels (e.g. multi-table driver, or even higher)
is unlikely.
So all we can do at the moment is an ACCEPT operation that skips
all further lookups in all header_checks tables.
