Microsoft 365 Email Security: Configuring SPF, DKIM, DMARC and Defender for Office 365

[@diskfelcore7597]

Awesome Breakdown; as a newer IT guy and our company is getting into DNS: SPF, DKIM, DMARC to use and offer to customers. Much better video than a few of the long ones on here.

Thank you, I’m glad you liked it.

@@TDSheridanLab Do you recommend and DNS Training Materials so I can get a deep understanding of DNS?

[@TDSheridanLab]

Well now I'm going to date myself a little bit. I originally learned DNS when I was studying for my MCSA on Server 2003. The 70-293 Network Infrastructure exam prep did a super deep dive on DNS. www.amazon.com/MCSE-Self-Paced-Training-70-293-Pro-Certification/dp/0735618933 Obviously Server 2003 is 20 years old now so that probably not the best resource for today. Here is the Microsoft Learn article on running DNS on Windows. learn.microsoft.com/en-us/training/modules/implement-windows-server-dns/ Depending on what you're trying to do with DNS, once you get the basics from either resource above then you can deep dive more specialized items like DNS for Azure or AWS, CDNs, etc.

Can I configure SPF, DKIM DMARK and Defender for Microsoft 365 email when my website is under construction/developement in a domain subdirectory?

[@TDSheridanLab]

Yes, configuring all of that is only dependent on Microsoft licensing and access to the public dns records of the domain.

Thank you for watching!

[@davidMacintire]

Was wondering if you could explain in what order does DMARC and Spoofing happen in M365. We have follow DMARC policy YES in M365 but have had some go into a user's Junk folder as spoofed and not rejected. They spoofed our Doamin, and our DMARC is set to reject.

[@TDSheridanLab]

What is the percentage of email set to?

[@capturethis69]

Saved me hours, thank you sir!

Great work! Thank you! 👍🏽

[@TDSheridanLab]

Your Welcome

Do we have to do anything in DNS when we rotate the DKIM keys?

[@TDSheridanLab]

As long as you have both keys in your public dns then you’re fine. If you didn’t create both records then you’ll have problems.

[@travelasia2023]

Background music is very distracting and not needed in my opinion.

[@TDSheridanLab]

I’m working on it, it’s my crutch.

[@Gentlestino]

Why do you have so much noise at the background ?

[@TDSheridanLab]

because e-mail connect is pretty dry.

[@jamesg871]

SPF, DKIM, DMARC... so confusing

[@TDSheridanLab]

Yep, nothing like having to bandaid a 20-30 standard for new threats! Thanks for watching.
