Please add a reverse DNS mapping for  2a01:4f8:131:2480::3 pointing to bugs.python.org. Apparently, otherwise email is considered as spam; see issue562

This is the mailer daemon response when trying to post a review on Rietveld with comments from Ralf Hildebrant. I've left only one error, but they're all nearly identical bar google's host and IP.

I'm intrigued, since psf.upfronthosting.co.za. doesn't seem to have an
AAAA record at all

$ host -t AAAA psf.upfronthosting.co.za
psf.upfronthosting.co.za has no AAAA record

Yet it seems to have IPv6 connectivity (which takes precedence for
connections)

A solution could be:

* enter AAAA and reverse records
or
* disable ipv6 for email delivery

Unfortunately I'm not the admin for psf.upfronthosting.co.za

Disabled IPv6 for now, Roché at Upfront will work on PTR.

I had an exact same mailer daemon reply about an hour after your message. So, perhaps disabling IPv6 alone didn't help.

The disabling of ipv6 reported by mmangoba does not appear to have been effective.  On the advice of p@trick, I added 'inet_protocols=ipv4' to the postfix config and restarted (around 15:28 Eastern) and that seems to have worked.  Serhiy was able to get a nosy email from the test tracker issue, at least.  No idea yet if rietveld emails are back to "just" being spam or are still blocked.
