I tried to mail ipv6@he.net from my main mail account admin[at]areaunix.org, but I'm not receiving any notice by the ticketing system. I then tried from another gmail account and I received it. Seems like my mails get blocked at HE from areaunix.org. I'm using GMail for domains there and I'm not listed in any rbl. Can you check what the problem is?
Thanks
Not seeing any connection come in trying to deliver mail from areaunix.org. Only thing in our logs involving that domain was a mail we sent on the 13th.
MTR over IPv6 to areaunix.org looks clean, and all MX seem to point at gmail.
Yes I received a newsletter on the 13th. Receiving works fine so far. But seems like my mails to ipv6@he.net don't arrive, because I don't get the Ticket Response. I'm sending a test email right now again, so you can check logs.
Might want to check your outbound MTA logs. Not seeing anything come in trying to deliver from your domain.
