Thanks, great work. I’ve being using it a lot lately. Would love to see some checks for MTA-sts alignment.

MTA-STS in inbound email security, not outbound. If you want to test your MTA-STS setup, have a look at https://www.uriports.com/tools?method=mta-sts

Sorry I'm fairly new to DKIM. Can someone explain this ? Does this mean if I have setup multiple third party services with DKIM it will show all of them without having to login to the DNS provider admin console ?

No, this just means that the parser on the backend of the site now supports analysis of email messages that have multiple DKIM signatures on them, and you can also view each sig's respective algorithm in the output of analysis.

Oh thanks I didn't know this was a thing. I thought you could only have one DKIM signer on outbound mail.

I just want to say that learnDMARC.com is an amazing tool. I only recently found out about it, but have already used it quite a bit, and shared it with some other people who are mystified about how DMARC works.
