Yeah, I've noticed this too, but I haven't looked into it. Until now :-)

The configuration of the servers is controlled via chef, and the chef
repository is at
http://git.openstreetmap.org/chef.git

There's a mailman cookbook, which has only one change made recently:
http://git.openstreetmap.org/chef.git/history/e9aa039648867546ebda79d0ceae2f6aa6f9621d:/cookbooks/mailman

The relevant commit contains the bug:

<http://git.openstreetmap.org/chef.git/blobdiff/e517f49bcdd9b1afac9809154c8d727f2bc96847..8604bd193412c0bf604d8b8e38b76d0e350f107c:/cookbooks/mailman/templates/default/apache.erb>

( http://bit.ly/1o9fn36 if the link above is borked)

```
-       <Location ~ "/pipermail/([^/]+)/(2004|2005|2006|2007|2008|2009)">
+       <Location ~
"/pipermail/([^/]+)/(2004|2005|2006|2007|2008|2009|2010|2011|2012|2013|2014)">
                ExpiresActive On
                ExpiresDefault "access plus 180 days"
        </Location>
```

So a possible fix is to remove 2014 from the end of that list until
the end of the year.

Cheers,
Andy
