Before I go looking for an SPF-specific mail list I'll ask here for help.
I've not before had any issues sending email to gmail.com users. Today I did and this is what google said: "<[email protected]>: host gmail-smtp-in.l.google.com[142.250.138.26] said: 550-5.7.26 The MAIL FROM domain [twodogs.us] has an SPF record with a hard fail 550-5.7.26 policy (-all) but it fails to pass SPF checks with the ip: 550-5.7.26 [192.185.45.95]. To best protect our users from spam and phishing, 550-5.7.26 the message has been blocked. Please visit 550-5.7.26 https://support.google.com/mail/answer/81126#authentication for more 550 5.7.26 information. w2-20020acaad02000000b0033a0e5ddb34si2085735oie.16 - gsmtp (in reply to end of DATA command)" When I set up SPF it passed the port25.com test. The IP address rejecting my message (192.185.45.95) is WEBSITEWELCOME.COM in Burlington, MA. Not google.com. And I assume the SPF issue is at websitewelcome's end. Am I correct? Regardless, that's not my IP address. Not being a SMTP guru I'm puzzled. Rich
