Hi,

I think this problem is a little more serious. It basically means that:

1. We have to disable TLSv1.1/1.2 if we want to be interoperable with 
certain systems that are (sadly) still widely used. TLSv1.2 is a major 
new feature, disabling it is not what we want.
2. Since you can't always disable TLSv1.1/1.2 in every application, it 
means we sometimes have to disable TLS altogether, or where TLS is 
required, you just won't be able to connect. This means openssl in 
wheezy is sometimes unusable.

The discussion here[1] seems to be misguided. Of course it's nice for 
every app to expose openssl options in its config, but openssl is what 
is broken here.

As for blaming the remote side - GnuTLS apps in wheezy are able to talk 
to MS Exchange (same exact servers having this error with postfix) with 
no specific configuration changes, having TLSv1.2 still enabled (e.g. exim).
