[ http://gmail.com/ | gmail.com ] started failing messages from domains which are correctly setup for SPF (and have been for some years): 550-5.7.26 Gmail requires all senders to authenticate with either SPF or DKIM. 550-5.7.26 550-5.7.26 Authentication results: 550-5.7.26 DKIM = did not pass 550-5.7.26 SPF [ [ http://nagler.me/ | nagler.me ] ] with ip: [139.177.203.52] = did not pass 550-5.7.26 550-5.7.26 $ dig +short txt [ http://nagler.me/ | nagler.me ] "v=spf1 a mx ip4:139.177.203.52 include:_ [ http://spf.google.com/ | spf.google.com ] -all" Sending to (paid) Google Workspace domains works fine. Nothing has changed on our end, and failures only started this morning. Any ideas?
