To meet the remaining goal * Non-subscriber posts are held for review by Moderators instead of being rejected. would require removing "Private" from "Send=", correct? Because the list probably receives more spam attempts than non-subscriber post attempts (I don't have recent data because the list has been set to "Send= Private" for years), I think I'll leave "Private" in place. Recarding SPF, because I'm not the site administrator, I'll simply forward WBrown's advice to him. Thank you very much for your advice, everyone! -- Best regards, Michael
