Hello people with a line into Microsoft… Starting just before 7pm UTC Feb 15th, we started seeing rejections for emails coming from sharepointonline.com:
2022-02-15 18:58:19 [26060] H=mail-am6eur05on2111.outbound.protection.outlook.com (EUR05-AM6-obe.outbound.protection.outlook.com) [40.107.22.111] F=<no-re...@sharepointonline.com> rejected RCPT <_redacted_>: SENDVRF1: Cannot verify sending domain or address As of right now, the MX record does not resolve: $ dig @8.8.8.8 +short sharepointonline.com mx 0 sharepointonline-com.mail.protection.outlook.com. sharepointonline-com.mail.protection.outlook.com does not resolve. That probably needs fixing pretty quickly. Graeme _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
