Re: [edk2-devel] "via Groups.io"

Per the groups.io FAQ...

Why Are Emails From Some People Changed To Be 'via Groups.io'?

The reason that some email addresses are changed to be 'via Groups.io' is because of something called DMARC. Some email services, like Yahoo and AOL, have set up their DMARC profiles so that we have to change all their users' email addresses to this form, otherwise the messages would bounce. This is not limited to Groups.io, all email groups services have to do this.

This is honestly a catastrophe: I see the same has happened to Phil's messages!

Compare:

http://mid.mail-archive.com/5ccaa1d4-714d-f785-e57d-bbd2c8e4596e@redhat.com
http://mid.mail-archive.com/6a59c2de-daf8-9555-d9ef-54a4734619d9@redhat.com

Both are attached, too.
