R. David Murray added the comment: smtplib in 2.7 doesn't know anything about RFC822 or any of the replacement RFCs. sendmail accepts a *string*, and doesn't understand or modify anything about that string except the newlines. It is your responsibility not to *add* the BCC header. What you want to do is put the BCC (and CC!) recipients in your toaddr list passed to sendmail, and *not* add a BCC header.
In Python3 smtplib has a send_message method that accepts a Message object, and that method uses the BCC to inform where to send the message and strips the header before sending. That is, smtplib's send_message method *does* implement RFC5322 behaviors. ---------- nosy: +r.david.murray resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue31052> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
