Just because he choose poorly with his email provider doesn't mean he should be allowed to be exploited Mike, although a friendly ribbing is still justified IMO ;) On Mar 20, 2017 9:27 AM, "Mike Hammett" <nanog () ics-il net> wrote:

I have an IP that was blacklisted by hotmail. Just a single IP. I have gone through the procedures that are referenced in the return e-mails. No response. My next step says something about a $2500 fee to have it investigated. Iknowseveral blacklists which are this way. Luckily, many admins do not use such lists.

In fact, let us not forget that these lists were mostly created with volunteers - somestilltoday. Many are very old lists. Enterprise networks select lists bysomesort of popularity / fame - etc.. Like how they decide to install8.8.8.8as first - its easy and they think its better than their local ISP they pay.... yet they always call the ISP about slowness when 8.8.8.8 is for consumers and doesn't always resolve quickly. It's a tough sale. Once had a customer's employee abuse their mail server - it made some lists. Customer complained our network is hosting spammers and sticking them in the middle of a problem that is our networks. Hard win. Took us months to get that IP off lists. That was one single IP. We did notallowthem to renew their contract once the term was over. Now, they sufferwithcomcast for business. ;-) Thank You Bob Evans CTOOn Sun, 12 Mar 2017, Pete Baldwin wrote:So this is is really the question I had, and this is why I was wanting to start a dialog here, hoping that it wasn't out of line for the list.Idon't know of a way to let a bunch of operators know that they shouldremovesomething without using something like this mailing list.Blacklistsare supposed to fill this role so that one operator doesn't have to tryandcontact thousands of other operators individually, he/she just has to appeal to the blacklist and once delisted all should be well in short order. In cases where companies have their own internal lists, or only update them a couple of times a year from the major lists, I don't know of another way to notify everyone.I suspect you'll find many of the private "blacklistings" are hand maintained (added to as needed, never removed from unless requested)andyou'll need to play whack-a-mole, reaching out to each network as youfindthey have the space blocked on their mail servers or null routed ontheirnetworks. I doubt your message here will be seen by many of the "right people." How many company mail server admins read NANOG? How many companies even do email in-house and have mail server admins anymore?:)Back when my [at that time] employer was issued some of 69/8, I foundituseful to setup a host with IPs in 69/8 and in one of our older IPblocks,and then do both automated reachability testing and allow anyone todo atraceroute from both source IPs simultaneously, keeping the resultsin aDB. If you find there are many networks actually null routing your purchased space, you might setup something similar. ----------------------------------------------------------------------Jon Lewis, MCP :) | I route | therefore you are _________ http://www.lewis.org/~jlewis/pgp for PGP publickey_________
