Wouldn't it be possible for a mailing list to give whitelisting
criteria on a webpage ?
Yes, it defenitely would, but then the questions become:
What format is the "whitelisting criteria" in?
What web page? ie: where does my MUA look?
And how do you pick a standard location that works for everyone?
The answer I came up with is a public database that any MUA can look in, and
that any list operator can create an entry in. The entrys would follow a
standard convention, and a standard method of quirying the database would be
developed for easy implimentation at the MUA end.
Basicaly it would just be a way of facilitating any out of band transfer of
information that would be required, but it could use smtp protocals for
backward compatability. uses could include IP addressess, PGP signature
keys, anything.
I guess it would be a sort of certificate issuer, only the contents of the
certificates would be up to the entry creator, and the only identity it
would verify would be that the entry creator had access to the address
mentioned in the certificate(s).
the database entry could even be a format declaration, and a website to look
at, but then you need to pick or develop a format declaration language, and
ensure that MUA's can "compile" it, and understand the resulting page.
Hedache city, and un-necisary complexity. The better choice is, I think, to
allow standard pieces of info, and write standard interfaces to them.
sorry i was rambling.
A mailing list could give its MTA name as outbound.bad.example.com and
the "host" command ("nslookup" on some OS's) could get a list
corresponding IP addresses, and check to see whether the sender is on
that list. Note that I specified name, not address. This allows the
list to move to a new ISP by editing its DNS zone entries. No need for
end-users to change anything in this case.
Yes a mailing list could give this and that, and it could be checked this or
that way. But a standard method, with standard tools, and a standard method
of accessing it would be usefull to many more people.
Tell them if you do "this", you don't have to worry cause the other people
just have to do "that" in order to understand. I think that's true
regardless of the subject.
