further you need to check your forward mx records are correct.

Indeed I have. I was the one that put them in, which fixed this
problem about ten days ago. Now it's back. In fact, I even posted the
AAA records on this very list.
And we have tried to explain that the A and AAAA records are not all you
need. See my

You also need 2 PTR records, one for your IPv4 address and one for IPv6
address. Very likely Gandi will need to do that for you, if they
support custom rDNS at all, and if they do not, you should not try
sending mail from their hosting.
