If you know the addresses that the journalists are using, why not
create an email address specifically, and exclusively, for their
purposes. Don't bother testing for spam. If the email message comes
from one of the addresses it's been created for then accept it,
otherwise delete it.

You only need to get complex if you don't know your journo's address
until s/he sends a message,
