the md5 digest code lives in PSM. If I remember correctly, mscott added
that code when he implemented the CRAM imap extentsion.
the were some performance problem when going out of process (to PSM) to
do the hash, and there were problems with
how to handle CRAM when PSM was not installed. I think that is why he
turned that code off.
mscott, please correct me if I am wrong.

mscott would be the best person to answer that.
