Bug#737921: [TLS1.2] gnutls only likes SHA1 and SHA256 certificates

[Ariel]

Hi, it is fine if gnutls26 is obsolete and was removed from the unstable 
repository, but we are talking about issues with Exim in Stable/Wheezy... 
you shouldn't just close this bug unless you update Wheezy to gnutls<newer>
IMHO... :-(
Or exim & others in stable should be recompiled with openssl... which looks 
even more "dangerous" as a change.
