> You're right, but as you point out that's not standard. It's not usually directly integrated in your mail client. It's just a hack. NNTP clients have all that baked in. While not standardised, I expect any decent e-mail client to handle mailing lists mostly automatically at least in that regard, e.g. Claws-Mail builds a nice menu from List-* headers. It is true that one usually needs to manually add filtering on the server side (in Sieve, maildrop or whatever you use), which is not as nice as the standard handling of news, but you can even automatise that if you’re willing to have emails containing random headers create the corresponding folders (which, of course, you shouldn't do). > I don't think NNTP requires more infrastructure on the server side (installing mailman vs. installing a NNTP daemon) but you're right that it does require installing a client on the client side (since everybody already has a mail client anyway. Most email clients also have NNTP support baked in, so the client side is not really an issue. However, newsservers have to keep at least a rolling archive of messages and possibly federate with others, whereas a mailman installation is mostly stand-alone and doesn’t even have to keep an archive if you don’t want to.
