Lately, we have been having an issue where an email is marked as SPF Neutral instead of getting a good old PASS from GSUITE when an email has been sent through the website’s contact form.
In our situation, we were using a 3rd party SMTP service that was integrated with our hosting. This service required modifying the SPF record to add an include statement, and set up the DKIM record. Great. Done. All looks good.
Everything looks exactly correct! The email was going out but going to Junk Mail. When we inspected the email it said SPF neutral, not permitted or denied, and not a PASS as we expected.
