It is not implemented yet.

I've written a similar code recently for the remote POP3 mailbox.
Check src/rpop3.c: rpop3_retr_recv(), which temporarily stores a message
on POP3 server, and parses and displays it.

        msginfo = procheader_parse_file(file, flags, FALSE);
        msginfo->file_path = g_strdup(file);

        msgview = messageview_create_with_new_window();
        messageview_show(msgview, msginfo, FALSE);

There is a documentation of LibSylph, but it is still only in Japanese.
