I just went and slapped someone (not really!), and had that fixed - it *should* have read 127.3.100.7, and means that their mailing policy is "opt-in" (ahem - NOT confirmed opt-in, which has a code of 127.3.100.10).

It's simply an alternative to 127.0.0.1, as we have had a couple of queriers say that was what they could use, and only what they could use - and it's now documented on the codes page. Thank you for bringing these to our attention!

EPIA member (whatever that is, +10 in IADB2)
EPIA is the Email Processing Industry Alliance. It's a cross-industry alliance of ISPs, Spam Filtering companies, Email Service Providers, and online marketers.
From the site at http://www.epialliance.org:
"We meet on a regular basis for the purpose of both working together, and making industry recommendations, to help ensure that we only deliver email which users want, and not email which users don't want. In other words, only wanted mail, and not spam. Each and every of our members is dedicated to this goal, and subscribes and adheres to the highest standards of email processing management. Our members work together to help each other and the industry to achieve the twin goals of maximum email deliverability, and minimum spam."
I happen to be involved with it, because it came out of the original Email Deliverability Summits which I organized.
The SPF record isn't listed (127.2.255.1), that would explain ten more points in IADB2. No idea what the reason for the last 10 IADB2 points is.
You missed:
127.0.1.255, which means "vouched", and is good for 10 points. "Vouched" means that they are personally known to ISIPP through industry dealings, and known to be senders genuinely striving to do the right thing.
