My SPF records have been valid for... oh 10 years or so, and haven't changed, but the last two days I'm getting intermittent bounces sending to gmail.com addresses from our customer domain. I've sent a couple of emails to [email protected] but I'm not sure it's monitored. Anyone else seeing such issues?
Hi. This is the qmail-send program at mail.fpunet.com. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. <[email protected]>: 142.250.105.27 failed after I sent the message. Remote host said: 550-5.7.26 This mail 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 [fpunet.com] with ip: [104.171.208.42] = 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 t8-20020a25f608000000b00dcbcc921879si776036ybd.61 - gsmtp dig @8.8.8.8 txt fpunet.com ; <<>> DiG 9.3.6-P1-RedHat-9.3.6-25.P1.el5_11.10 <<>> @8.8.8.8 txt fpunet.com ; (1 server found) ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 43644 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;fpunet.com.
