:contains, :matches and :is are not helpful here

Have you tried using the "exist" test from the sieve rfc

5.5. Test exists

Usage:   exists <header-names: string-list>

The "exists" test is true if the headers listed in the header-names
argument exist within the message.  All of the headers must exist or
the test is false.

The following example throws out mail that doesn't have a From header
and a Date header.

Example:  if not exists ["From","Date"] {
             discard;
          }

i have not tried it myself but the core of rfc 5228 is reported to be fully support by pigeonhole
