My biggest problem with SPF, DKIM, DMARC is when you go to test this crap there's really only commercial apps. So people who are setting up things for a non-profit or a personal project are either forced to pay after doing 3 or 4 test emails or you wait like 24 hours or some crap.
And all that just for the privilege of being able to send email to some gmail accounts. Trying to get email to properly encrypt is pulling teeth and yet I still get hundreds of thousands of spam a month on my gmail account.
Any time I have to set up an email server on a new system I just kind of die a little.
I built a free DMARC/DKIM/SPF checker: https://dmarcchecker.app/. No usage limits, no ads—just a small footer link to one of my other projects. Made it for the exact reason you mentioned.
This is awesome. Thanks! Sensible, easy to use, easy to understand the results.
I've been trying the google one, for example, and it doesn't even work. "request timed out." Fishy, because yours works great.
much appreciated!
Yopmail does verify and show these results for free when receiving a mail, this not even being their core feature
That’s good to know. I’ve not seen it mentioned anywhere. The tools I’ve used in the past give me 3 or 4 test emails before they require me to sign up.
You can always first send it to yourself and read the Authentication-Results header. Though even Gmail displays SPF/DKIM/DMARC status when you view the raw source of an email.
Which works great unless you're trying to debug gmail refusing your emails because of some issue or another.
