Jack added the comment: I think you missundersttod. I showed the example page just so you would understand what I am talking about. Let me explain it better: msg['Subject'] = 'The contents of %s' % textfile msg['From'] = me msg['To'] = you Works. msg['Subject'] = 'The contents of %s' % textfile msg['From'] = me msg['To'] = you msg['CC'] = x msg['BCC'] = y won't work. It doesn't know what is CC and BCC. This is why I opened this request to modify the package to support it. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue29771> _______________________________________
