Bug#711817: pu: package dkimpy/0.5.3-1+deb7u1

[Scott Kitterman <debian@kitterman.com>]

Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: pu

python-dkim has a bug that causes signature verificaton to fail in some cases
that is affecting stable users.  It's fixed upstream and in unstable and I've
been asked to get it fixed in stable as well.  The fix is quite compact and
should have negligible regression risk.
