    Resolution: Not A Problem
      Assignee: Daniel Gruno

I am closing this ticket as 'not a problem'.
mail-archives hasn't gone away yet, and when it does, we have a plan for redirecting properly
to the new system, so no links will get lost (it's a matter of placing a very simple RedirectMatch
directive in httpd). 

Furthermore, we have a strategy for what would happen in the event that we move away from
lists.apache.org in the future and on to something new. But this is hardly something that
should (or can) be addressed just yet.

>          Issue Type: Bug
>          Components: Mail Archives
>            Reporter: Sebb
>            Assignee: Daniel Gruno
>            Priority: Minor
> A permalink to a mail message should always be able to find the same mail.
> This is achieved for the existing mail archives by using the message-id.
> However the Pony Mail solution (as installed) uses a shorter hash generated from some
of the mail contents.
> As a result, message links in future will be of two forms:
> http://mail-archives.apache.org/mod_mbox/httpd-dev/201606.mbox/%3CCACsi252b-KUB-HtPQTe7Ti%2Bxrek2XK%2B%3DuKvfcO9diCN0Dg1kKQ%40mail.gmail.com%3E
> and
> https://lists.apache.org/thread.html/Zfp0souj6y08k06
> The latter link is obviously much shorter, but has the disadvantage that it cannot be
compared with existing links. Also one cannot see which mailing list it is from.
> Futhermore, the hashes are not stored in the mbox file, so it's not possible to search
for the message in offline copies of the mail. AFAICT the hash only works with the correct
version of the PonyMail software.
> I think the same permalink style must be retained for any mail archive system that is
used by the ASF.
> What happens if (when) the mail archive software is changed again?
> Will there be 3 different permalink styles?
> I think this needs to be addressed urgently, before too many new style permalinks are
