grass-dev subscription bounced because osgeo6 failed to deliver to Runbox

[dovsienko]

Hello support.

I have been a subscriber of the grass-dev mailing list for a while, and recently my subscription started to bounce with the diagnostics below. As far as I understand it, osgeo6 had tried to deliver the message in IPv6-only mode, and Runbox is an IPv4-only service. That said, I have been receiving the list messages up until today, so the best first place to check seems to be osgeo6. Could you check please?

Thank you.

Apparently only two mails to runbox.com bounced today. One at 04:33:09 PDT to you and one at 05:01:50 PDT to someone else. 23 were delivered to runbox.com successfully. So it was probably just a temporary DNS hickup (both bounces have: "Host or domain name not found. Name service error for name=mx.runbox.com type=AAAA: Host found but no data record of requested type").
