I'm seeing many emails to edk2-devel being flagged as spam and ending up in my Spam folder, starting yesterday.
This might be an isolated issue with my mail provider (Fastmail), but thought I'd mention it in case it's more widespread.

For example, Mike's email "Re: [edk2-devel] edk2-platforms, continuous integration, testing, and you" about moving the meeting to 10am pacific on Tue Jan 17th was flagged.
Some of the headers are:

X-Spam-known-sender: no ("Email failed DMARC policy for domain"); in-addressbook;
 53d73d40-71d5-42b2-826f-50ae0b28b233 ("Autosaved")
X-Spam-sender-reputation: 500 (none)
X-Spam-score: 9.4
X-Spam-hits: DCC_REPUT_00_12 -0.8, HEADER_FROM_DIFFERENT_DOMAINS 0.25,
  MAILING_LIST_MULTI -1, ME_HAS_VSSU 0.001, ME_SENDERREP_NEUTRAL 0.001,
