Phab emails down

Hi,

Phabricator emails don’t seem to come through, I suspect something is going on with our email provider (Sendgrid).

I can’t debug it more for now as it seems that TFA was se tup on our account recently and it is using someone else’s phone, I believe they are in Europe. We may have to wait tomorrow (European time) to get more info.

I’ve updated the api key.

that was a red herring - the problem was that all gmail receivers were put on the bounce list after the gmail outage; note that that also means those emails will not be re-delievered.
Please ping all reviews that you want answers on. Thanks!
