I feel Customize is the right place to put certificate exceptions. The user can set their custom.el file to be GnuPG-encrypted if they are concerned. >> If we provide that simple UI, plus some help messaging, I think we can >> disable DHE by default.

Nikos advocates (and I agree) that it's prudent to add "!DHE-RSA:!DHE-DSS" to the default priority string. We can make it easy for the user to remove that exclusion or make a specific exception as we've discussed. Ted
