broken links in the news section on the offlineimap webpage

[Steven Vancoillie]

Hey, I'm not sure this is the correct place to report this, but the
links in the news section on http://offlineimap.org seem to be broken.
For example, the following link:

http://offlineimap.org/OfflineIMAP/offlineimap/releases/tag/v6.5.5

gives a HTTP 404 error from github for me. Replacing offlineimap.org
with github.com works.
