Not sure they've changed that much since. I have a mail server, and while it's not blacklisted by any of the bigger ones (MS, Google and so on), my whole /24 block(!) is on the blacklist of whoever is providing spam filtering to Slackware (signed up for their mailing lists while I was still using Google as a mail provider).

Because the provider says: "If you are on a network that is known for allowing email marketing to occur, you may be out of luck as well. If you aren't doing email marketing consider a different network."[0] I haven't yet gone through and actually contacted them especially since my IP is included in their "worst" category[1]. It's also the only place I've had a problem with so far, so not worth the hassle yet.
