@wdormann@infosec.exchange @nyanbinary@infosec.exchange Google starting getting picky about matching forward/reverse DNS, SPF, DMARC and DKIM above certain mail volumes, etc. It’s non-trivial to successfully deliver to GMail these days. Which is not to excuse the vendor apparently not even trying. Just pointing out that “can deliver email to GMail successfully” is a sign one is doing quite a lot right. (IIRC some large open source dev mailing lists also basically gave up on trying to deliver to GMail.)
