Public bug reported:
http://bazaar.launchpad.net/%7Emailman-coders/mailman/2.1/annotate/head:/doc... line 86 includes a link, "Reply-To Munging Considered Useful", pointing to metasystema.org/essays/reply-to-useful.mhtml archive.org shows this document disappeared sometime between late 2013 and mid-2014, and if it's currently visited, your browser gets redirected through a large number of what I can only assume to be spam domains.
I don't know if there's any policy for what to do with dead links in documentation, but a faithful reproduction of the document seems to live on http://marc.merlins.org/netrants/reply-to-useful.html (unchanged for the last 11 years based on a swift visual inspection via archive.org), so updating the link to point there seems to make sense.
** Affects: mailman Importance: Undecided Status: New
The source for all these documents is the branch at https://launchpad.net/mailman-administrivia/. This particular issue was fixed in rev 117 of that branch on 2 March 2015. Unfortunately, the process of rebuilding the docs from the .tex source following that change appears to have been overlooked.
Thanks for your report.
I will fix it.
