rfc2822_missing_headers — rfc2822 conformance
rfc2822_missing_headers = "reject"
rfc2822_missing_headers = "allow"
RFC 2822 requires that all messages consist of headers and a body, separated by a blank line. By default, Momentum will reject messages that are missing their headers, but by setting the Missing_Headers option to "allow", it will accept those messages and treat them as header-less messages, prepend trace headers as normal.
rfc2822_missing_headers is valid in the global and the pathway scopes.
