Hi, I was catching up on the recording of JMAP's meeting for IETF99, and this seems really fascinating to me. I have one straight question though; how is S/MIME going to be supported for JMAP? The JMAP mail spec seems to be silent on this, and maybe the spec needn't concern itself with S/MIME, but I would still like to get your views on S/MIME over JMAP, and the potential issues which could come up with trying to integrate S/MIME with JMAP. Thanking you, Vaibhav Singh
