To investigate that question, I would look for INPUT_MAIL_FILTER,
InputMailFilters in cf/README and a couple of files in the cf/m4
directory in your copy of the sendmail source.

In particular, this paragraph in the 8.14.7 version of cf/README
looks like a clue about the problem:

  Note that setting `confINPUT_MAIL_FILTERS' after any INPUT_MAIL_FILTER()
  commands will clear the list created by the prior INPUT_MAIL_FILTER()
