Hello Everyone, I am currently drafting a document regarding accepting email on ipv6 and building our white list database (it will eventually be either six.ascams.com or sixwhite.ascams.com) Ref: https://tools.ietf.org/html/draft-tzink-ipv6mail-whitelist-01 The actual practical implementation is so simple and easy:, simply use it in reverse of a blacklist, score all incoming ipv6 emails +1000 and if listed on six.ascams.com -1000 (and if listed with whitelist.example.com -1000 - etc etc) Defining the actual processes for white listing itself, is not as easy as it may seem... Black list: for example superblock.ascams.com: First time de-listing (takes anywhere from 24 hours to 7 days) Second time de-listing (takes anywhere from 7 days to 3 weeks) Third time listing is a semi permanent block (discussed in public) Fourth time listing is permanent, even if the ipv4 resource re-allocated On White Lists, the process is not as clear or obvious as one may think as firstly the address space has 2(128) addresses, sec issues ( https://tools.ietf.org/html/rfc5782) etc etc etc But, notwithstanding that, the actual listing & de listing is also, reasonably simple: For example: the same process as blacklists, if multiple users file complaints, the ipv6 entry is revoked, re-instated, etc etc and this is where I am at now. The actual listing entries, sure, we already have a few hundred good/known ipv6 email servers, but how do admins go about adding themselves to the white list? Obviously it has to be free, open, fair and anyone has to be able to add themselves. But, it is the actual adding, bots, trust and other issues that is still challenging. (and, yes, I have read BITAG (bitaq) etc as well as all the other copious amounts of drivel, diatribe and POV out there) One idea is for admins to go through manual verification process, for which volunteers would be required, Another idea is that In the TXT answer, for white listing, the email address of the ipv6 abuse@ is to be published and for the entire database to be available (like the RIPE whois) - which has given rise to an idea that all servers (people providing services / providers of services as opposed to users of) - should have their own, separate resource listing... There are of course many other ideas as well, but the reason for my post is: Do you have any value, comment or idea you could add to this? thanks! Andre
