[GreenKeys] META: Did Greenkeys suddenly change hosts?

[Jeff Albrecht]

Gil and list,

About an hour ago I sent the following to a contact form attempting to 
get in front of the DNS / Post master as on the 20th of this month they 
made a breaking change to DNS. Just moments ago I got a flood of 
delivery of over thirty emails. I guess they got my message to the 
correct eyes. Although they implemented a slightly different fix that 
had probably been their original attempt.

        /Hoping to get this in front of an email administrator /
        postmaster for qth.net Someone responsible for DNS at qth.net/

        /I am an email administrator for the domain rodaw.com among
        others. Several days ago on or about the 20th we began
        experiencing email rejection of a previously functioning address
        'greenkeys-bounces at mailman.qth.net' Previously working for years./

        /postfix maillog.log excerpt; /

        /"NOQUEUE: reject: RCPT from unknown[69.16.227.189]: 450 4.7.25
        Client host rejected: cannot find your hostname,
        [69.16.227.189]; from=<greenkeys-bounces at mailman.qth.net>
        to=<jeffa at rodaw.com> proto=ESMTP helo=<mailman.qth.net>"/

        /We believe the problem is that there is no 'A record' forward
        reference for 69.16.227.189 There are two entries for
        mailman.qth.net butt not for 69.16.227.189;/

        /mailman.qth.net.        300     IN A       104.27.169.135/
        /mailman.qth.net.        300     IN A       104.27.168.135/

        /There is a reverse in-addr.arpa PTR (but no A record)/
        /189.227.16.69.in-addr.arpa. 300 IN PTR     mailman.qth.net./

        /Hence since our MTA can't resolve 69.16.227.189 with
        mailman.qth.net email is rejected as part of our spam protection
        at EHLO./


Working for me now.
