Description
In gitgitgadget/git#691 I added Philip Oakley to the CC list, with his email taken from the CC list in this message.
Apparently this email account does not work anymore, but I was not made aware of that by Gitgitgadget, I realized it when I received a "Mail Delivery Failure" email when I replied-all from my email client to a comment on my series.
I think it could be nice if GGG could add a comment on the PR if one of the emails in the CC list is unreacheable. I guess that would mean monitoring the emails sent to the GGG Gmail address, which may or may not be feasible. I'm just throwing the idea out there.
[Meta question]: apart from manually checking the most recent commit for each person in the CC list with git log -1 --author '<some person>'
upstream/master, is there a builtin way in Git to check the "currently in-use" email address of someone ?
