Google randomly breaks mail from the real world of SMTP all the time.
As long as other gmail users and outlook.com users can get their mail
in, they're happy; trying to send reliably from anything else is a
generally waste of effort.

That said, sending via an ISP's smarthost may have a better chance of
success.
