Bugzilla

This is the only @mozilla.com email I receive that comes with this warning, and it is not routed to my Spam folder by Gmail. If you can identify other From: @mozilla.com emails that contain a domain _other_ than `mozilla.com` in their DKIM header, I suspect they too will show this issue. I checked the most recent TLDR newsletter emails, that are sent From: @mozilla.com, through a different third-party mailing service; they say:

`dkim=pass header.i=@mozilla.com`

rather than the Wikimo header, which says

`dkim=pass header.i=@amazonses.com`

Which is I assume why those other ten emails did not contain an impersonation warning. So I encourage fixing the DKIM header to be signed for domain `mozilla.com` as a first step towards correcting this issue, simply to align it with our other uses of DKIM, and if that isn't sufficient to resolve the impersonation warning, further investigation would be possible without that muddying the waters.
