According to header_checks(5) this is implemented by the cleanup
server. header/body_checks are documented as parameters on the
cleanup(8) manpage. They are not documented as parameters on the
smtpd(8) manpage.
All this confirms that header/body_checks are a cleanup(8)
feature, not an smtpd(8) feature, Meaning, it's pointless
to specify this on the smtpd(8) command line.
