At the M3AAWG meeting (see previous post) there was considerable interest in the proposal on domain-based whitelisting information. However there is no operational experience which would allow anyone to see how this would perform.Now you can test 🙂 Continue reading “Whitelisting DKIM-signed domains”At the 41st M3AAWG meeting in Toronto, we got the opportunity to present the dnswl.org project to a wider community.The slides linked below were shown – please let us know if you have any questions or further input.I hope we will be back for the M3AAWG meeting in Munich next year.dnswl.org will remove a workaround-file for Postfix < 2.8 from download on August 31st 2017.

If you are not managing the IPs of your own mailservers at dnswl.org yet, you should do it!Continue reading “How many legitimate mailservers are there?”TL;DR: Sign up to the dnswl.org Self Service and start managing the reputation of your IPs.Continue reading “Do you manage the reputation of your IPs?”dnswl.org limits the use of the public nameserver infrastructure to those doing fewer than 100’000 lookups per 24 hours and to non-commercial use (see here for details).

Of course we are happy about the great up-take of the Self Service in the community.The same call, in code.
The capture above came back as markdown. These examples add a key, so you get browser rendering, proxies, and concurrency on dnswl.org.
import { SpiderBrowser } from "spider-browser";
const spider = new SpiderBrowser({
apiKey: process.env.SPIDER_API_KEY!,
});
await spider.connect();
const page = spider.page!;
await page.goto("https://dnswl.org");
// No selectors, no schema. Spider reads the page and names the fields.
const data = await page.scrape();
console.log(data);
await spider.close();import { Spider } from "@spider-cloud/spider-client";
const spider = new Spider({ apiKey: process.env.SPIDER_API_KEY! });
const result = await spider.scrapeUrl("https://www.dnswl.org", {
return_format: "markdown",
});

Fields you can pull.
Spider names these from the page. The capture above came back as markdown; the same
call with return_format: "json" returns them as keys.
