My cloud email provider supports DMARC. Do we still need to implement it?
Many of the of the large cloud email providers (Google, Microsoft, Yahoo) do provide DMARC support by default but only for their consumers. Meaning, if you are using gmail.com, yahoo.com, outlook.com, live.com, and so on, then you are protected by DMARC. However, your organization will still need to implement DMARC even though you are using a …

DMARC
Domain-based Message Authentication, Reporting and Conformance (DMARC) is an email-validation system designed to detect and prevent email spoofing. It is intended to combat certain techniques often used in phishing and email spam, such as emails with forged sender addresses that appear to originate from legitimate organizations. Specified in RFC 7489, DMARC counters the illegitimate usage of the exact domain name in the From: field of email message headers.[1]

It was DNS... : homelab
Nothing was working. Let's get this out of the way: it was DNS. I had turned off my ESXi box that had my secondary Windows Server 2016 VMs on it, and sure enough I sit down about 30 minutes ago and DNS? Nope. Chuck Testa.

OK, to the iDRAC! cue Batman music "Blah blah blah foreign configuration on the adapter" My heart stops. I lean over to the server stack next to me (it's on a $20 coffee table I got from Amazon), and two drives are ejected from the R710. So I call out to the horde downstairs "Hey, are you guys having trouble watching your youtube shows and stuff?" Collective "Yes....." comes back. I bring my 3 boys (8, 6, 3) upstairs and calmly ask them if they touched the server. Nope. Nope. "Uhhh no?" the 3 yr old says.

ORLY? So I ask him gently about it, and remind him that I'm not mad, but this is a learning moment and it's important that he tell me the truth so we can learn the right lesson. He admits to pushing the eject buttons because he wanted to see inside. That's my boy. Homelabber in the making. My 6yr old promptly got out his markers and construction paper. 5 minutes later he puts a "Do not touch" sign on my server stack. He's very thoughtful and creative.

SO.... I think I'll get a rack and mount that sucker in the top.
