Anything in mynetworks (every pod, and the LAN) could relay through 47.181.8.84 as any domain, which receivers treat as spoofing and charge to this IP; that is how NoReply@HarmonyHomeLoans.net drew Gmail's 5.7.26. Relaying off-site now requires a kamocrm.com (or subdomain) sender; others get a 4xx, so a campaign pointed here by mistake cannot mass-suppress. Signed-in submission and mail addressed to us are unaffected.
