Hi,

Today, many emails from the bug tracker have been rejected by Gmail
servers. It seems it was because the server used its IPv6 address and so
we fail into some strange policy of Google.
I first setup this workaround:
https://blog.hqcodeshop.fi/archives/122-Fixing-Googles-new-IPv6-mail-policy-with-Postfix.html
which seems to work after some tests.

After that by reading
https://support.google.com/mail/?p=ipv6_authentication_error, I
implemented DKIM for tryton.org mail server (there was already SPF).
Maybe later I will try to implement also DMARC.

I have left the workaround for now as Google may still block for some
times.

So please report me if you think you have issue to receive notification
emails from tryton.org

Thanks,
