It's the same format used in the pre-tcp days, more or less.

We added the X-topics field (?), and it turns out that both the topic passed in and the whole field have newlines at the end. So you get an extra newline that breaks off the headers from the text.. fprintf(out, "X-topics: %s\n", "[OT]\n"); or equivilent. Obvious :-) Interestingly, My mac's mail.app isn't having any problems with the discontiguous headers. Both display and sorting into the "Piclist" (which I have based on "to:" field) are working fine. I wonder if that's a feature, or a bug?
