Undelivered Mail Returned to Sender to gmail accounts from @torproject.org
We are having the issue that mails get undeliverable to gmail from our @torproject.org mails.
From @mattlav: "The last Welcome Email I sent to 571 new contacts was received by 49% of them."
The mail I get from Mail Delivery System MAILER-DAEMON@submit-01.torproject.org is in https://gitlab.torproject.org/-/snippets/174
