Re: google bouncing emails - ipv6 ptr problem?

So instead implementing strange workarounds, one should search, find,
understand and fix the real problem.

Google bounced my mail because of a temp error. I changed nothing
in my DNS or DKIM. It's their bug, not mine.

I don't expect your setup is obviously broken and also I don't want to
attack somebody. Sorry if that was misunderstood.


which is simply not true /from my/ experience. I send >10k messages per day
to Google mx servers and never noticed such problems.

but in general I often notice people tend to claim it's *always* Google's fault OK, maybe I'm in a magic Google whitelist because of my volume but I'm not aware of this.

Same here as Wietse said. We have not changed DNS for the mailer for years, but once in while if Google fail to resolve the IPv6 PTR they reject the mail. With the same setup to the same destination and the very same content some minutes later it works. This is annoying to say at least. Maybe you simply have been lucky until now or your DNS records tend to stay in the Google DNS cache for a longer time.
