Setting up SPF looks straightforward until you start dealing with multiple mail providers, includes, and DNS records. What mistakes have you encountered most often—multiple SPF records, missing senders, too many DNS lookups, or incorrect policies? I'd also be interested in recommendations for tools that validate an SPF record before it's published. | |

I know this thread is a bit old, but I just ran into this exact problem last week. The most common mistake I see is people copying an SPF record from one provider and adding another include line without checking the DNS lookup count. That quietly breaks email delivery. Have you tried using a tool like SPF Record Checker or Mailhardener? They show you the exact lookup number and flag duplicate records. What policy are you leaning toward for your setup? | |

The biggest mistake is having multiple SPF records, which causes failures. For validation, I regularly use an SPF checker to catch issues like exceeding the 10-lookup limit before publishing. It also helped me avoid missing authorized senders and get the `~all` policy right. | |
