[svlug] Gmail & Googlemail subscribers' subscriptions were disabled (welcome back)

[Rick Moen]

Correcting, in case the typos weren't obvious:

> Earlier this evening, 387 subscribers to this mailing list who are using
> either GMail or a domain served by Googlemail had their subscriptions
> disabled by Mailman pretty nearly all at once, on account of excessive
> 'bounce score', which mass-damage upon examination resulted from
> lists.svlug.org running headlong into a Google antispam policy rejecting
> mail from an host with IPV6 SMTP transport if the AAAA DNS record
            ^^ 'any'
> doesn't have a matching PTR reverse.
> 
> I corrected this by locking down our MTA (SMTP software) to deliver
> using IPV6 for now (as we don't currently really need IPV6 SMTP), and
        ^^^^ 'IPV4'
> (separately) Sarah Newman at prgmr.com was kind enough to quicky create 
> a PTR record to match our AAAA reference record -- just in case we ever 
> _do_ need IPV6 transport for SMTP, and care about GMail delivery.

I was a little tired at the end of all that.
