Great tool, one bit of feedback on the log report. Perhaps you can highlight the passing line in the SPF record, I have about 100 of these "The ip4 mechanism does not match." and then a lot of "The include mechanism matches and produces a pass result."

Maybe you can highlight the passing statement? - https://app.screencast.com/Hu5ybB6K3fd9R

I've given it a go. I recommend also https://mxtoolbox.com/dmarc.aspx I have no affiliation.

Seems that this tool actually validates your email and checks its alignment vs. just checking to see if there is a dmarc record on the domain.

Thanks for the feedback, much appreciated! It looks like you've flattened your SPF record, causing a large number of log messages. I'll see what I can do to better highlight the line that produces the 'pass' result.

Thank you - and would you be open to white labeling?

We've just launched the app this week. While white labeling is a possibility down the road, we're currently focused on refining it and gathering user feedback.

Hey, this comes at a perfect time for me. I had posted my app on Betalist about a week ago and received a vulnerability report about incorrectly configured DMARC from a security researcher. I made the fix but wasn't confident about it. Shortly after, I received a couple more similar emails. With this tool, my first check failed, citing an invalid SPF record. (I had an extra `.` at the end of my TXT record). Now, the…

DMARC itself contains some extra checks (alignment check).
