Hello Ops, gmail bounces some of our messages because of SPF not passing:
550-5.7.26 Your email has been blocked because the sender is unauthenticated. 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 [] with ip: [185.149.214.63] = did not pass 550-5.7.26 550-5.7.26 For instructions on setting up authentication, go to 550 5.7.26 https://support.google.com/mail/answer/81126#authentication 5b1f17b1804b1-4804d8ba409si18736685e9.65 - gsmtp (in reply to end of DATA command)) But our SPF records are just fine for that IP? https://mxtoolbox.com/SuperTool.aspx?action=spf%3afh-muenster.de%3a185.149.214.63&run=toolpage We are also no mass sender exceeding 5000 mails per day, so we should be fine with SPF only. Any hints on what to check?
