My takeaway is there is no bug. My takeaway is that his test email bounced because he didn't have the reputation Viva does. Emails are handled on a reputation basis, this is why we use email service providers like Sendgrid, Mailgun, Postmark, etc.
Social network is not good for the poor guy. I already regret replying to him in the first place but I cannot delete.
What test email? I see no mention of a test email in the blog post. The mail that bounced was the one with the verification link from Viva.
Of course, they do have leverage over “marketing email” senders since they can block it and no one will complain, so those senders always have impeccable compliance with every year’s new “anti-spam standard.”
