You should consider implementation of TLS_FALLBACK_SCSV [1] too.
Be sure the patch for CVE-2014-3568 is applied to your OpenSSL library.

I was in touch with new ejabberd maintainers and they don't have time for
backporting all the packages for wheezy. It's a lot of work due to
complicated dependencies. I started with the work, but didn't have time to
finish it either. Can come back to you once available.
