- .href_url.query_params contains '&url='
not:
- .href_url.domain.domain matches '&url=[^\\&]*eodcnetwork(?:direct\\.com|\\.org)(?:\\&|\\/|$)'
not:
- sender.email.domain.root_domain in ('eodcnetworkdirect.com', 'eodcnetwork.org')
any of:
all of:
- sender.email.domain.root_domain in $high_trust_sender_root_domains
not:
- headers.auth_summary.dmarc.pass
- sender.email.domain.root_domain not in $high_trust_sender_root_domains
