I've been thinking about this some just recently; my opinion has shifted
somewhat. I still think that the patch I previously provided is the best
solution.

However, openssl-1.0.0-beta2 is out and it still does not enable SHA-256 by
default, even though it's in standards-tracks for default usage, as noted
above. More and more, I'm seeing real world usage shift towards sha-256 away
from SHA-1 or even MD5.

Exim *shouldn't* be getting involved in policy and loading SHA-256 manually,
but I think that pragmatically we're going to have to.

Tony, Nigel, any thoughts on this?
