mailman's mailing list archives at biopython.org/pipermail/...

The single largest group of broken links reported via the Google webmaster tools, and also noted by @mmokrejs (see http://mailman.open-bio.org/pipermail/biopython-dev/2016-April/021345.html) are URLs like this:

http://www.biopython.org/pipermail/biopython/2011-January/006979.html

This page is still available via the primary OBF mailing list domain name:

http://lists.open-bio.org/pipermail/biopython/2011-January/006979.html

They are also available via this secondary alias:

http://mailman.open-bio.org/pipermail/biopython/2011-January/006979.html

Ideally we'd automatically redirect http://lists.open-bio.org/pipermail/* to http://lists.open-bio.org/pipermail/* which was easy under Apache, but becomes harder under GitHub Pages.

See also #19 and #32 for more general issues about broken links.
