After investigation, several IPs used by gmail to send the email were
blacklisted. I had a tough time explaining to the customer that it was
gmail's fault to still use this IPs to send their email. Gmail never
acknowledged the problem and didn't change the outgoing IP addresses.
The problem was only "solved" when the blacklisting expired. And this
was to a paying customer with 200 Gsuite accounts...
But isn't that just perfectly serving on the main point of this entire
thread?
"Hey, we're Gmail - you better do not put any of our IP addresses on a
blacklist!"
Best,
