With some limitations I would be happy to host it. Currently I am thinking about starting to host another list and having multiple useful lists would be nice. The targets/content of each list would be (partly) different. Below is how I'd do it if I'd be hosting it, on request I'm happy to host it and to coordinate it. The limitations: - It would get multiple output options, including one where you can use it to use custom actions (like greylisting). - Downloads could be limited to hourly or daily downloads per IP (to prevent people using up to many resources). - People could sign up to a newsletter to get notifications of policy changes. - Downloading/using it is free and on the risk of the person/company that downloads and uses it. - Contributing to the list could be done by sending an e-mail and/or using an online form. Also note: - Donations/money won't be accepted. - On some pages regarding this free service I might put ads (the files with the information won't contain any ads that could cause problems with postfix). I also want to publish a list with known not working rDNS hosts with mail servers to lower the number of F/P while blocking on not matching rDNS. With kind regards, Mark Scholten
