The List-ID standard looks like the thing I was looking for. Having a
virtual domain name built into the name of the list (or using the unmanaged
list name space) seems a good idea, as it decouples the list from the
actual host which provides it, and from the particular mailing list software.
(Lists, particularly newly created lists, do move from host to host within
If you think your list might move between service providers you could still
register a virtual domain for your list (e.g. hockey-players-list.com)
which would be able to move with you (I know this is unlikely in your case)

Most of my filtering is done by Sender, and I am pleased to hear that you
tell your users how to filter in the list documentation. Most lists dont
provide any advice in filtering, which is why they get so much traffic
asking for the list name to appear in the Subject header.

Trivial for me, as I use a proper mail system - not so trivial for the
millions who have to use a proprietary mail system. I have just fired up
my Groupwise client and all it will filter on is Subject, From, To, Cc and
Message contents. Outlook is similar, ccmail is worse.
If a List-Id specification became standard then we could pressure the mail
system vendors to support it. One of the big growth areas is in group working
tools - I think the user of the future will see named streams of information
which they will turn on and off and not care too much about how they arrive
at their system.
(I see no-one has mentioned Newsgroups in the List-Id spec - maybe there should
be provision for mailing lists which are gatewayed to/from newsgroups ??)
