If anyone is interested in the "MIME-Version header", I have played with the mime stuff and read rfc1341 to understand better how this stuff works. I am enclosing a subset of MimeWriter.py which will allow the functions to put the "MIME-Version: 1.0" header in the correct place. I would like to warn everyone that I am not a python programmer, and there might be a better way to do this. The changed subset: def startbody(self, ctype, plist=[], prefix=1, version=0): for name, value in plist: ctype = ctype + ';\n %s=\"%s\"' % (name, value) self.addheader("Content-Type", ctype, prefix=prefix) if version: self.addheader("MIME-Version", "1.0", prefix=1) self.flushheaders() self._fp.write("\n") return self._fp def startmultipartbody(self, subtype, boundary=None, plist=[], prefix=1): self._boundary = boundary or mimetools.choose_boundary() return self.startbody("multipart/" + subtype, [("boundary", self._boundary)] + plist, prefix=prefix, version=1) This will only place the "MIME-Version: 1.0" header if you are using the <!--#mime --> tag. This sends a multipart/mixed message. Clarence T. Pate
