Sorry, but no. A mailing list puts its own envelope return address on the message so with a reasonable SPF record, SPF will normally succeed. (If the mail is subsequently forwarded SPF will fail, but that's not unique to mailing lists.) DKIM and DMARC do not get along with mailing lists, but SPF is OK, at least as OK as SPF ever is. tl;dr nanog needs to put back its SPF record. It'll make some systems such as Gmail considerably more likely to accept the mail. R's, John
