You are entirely correct regarding 0.9.8+ for SHA-256. It seems it is a
problem for Owl but 0.9.7 should really get retired. In general one can
always write optimized code that outperforms generic OpenSSL
installations so as I noted initially there is a need for optimization.

That is also a great idea as hmailserver wasn't even something I had
heard of before I wrote the patch. Is this an item you have the time
and interest to do?
If someone can point me to a license acceptable SHA-256 implementation
or someone can add one that would be greatly appreciated.
I want to support the patch I wrote as I wrote it for a friend but
posted it because I expect it may be of use to someone else as well.
However, my free time is quite limited and I wrote this as a short break
from work on my project. I welcome any updates to the patch that make
it acceptable for the jumbo patch as well as feedback on what items I
will have to address myself.
James
