Email was very open in the beginning of the internet. Before there were bad actors. Since that time, email has become the internet service most used for bad purposes, to deliver bad payloads, spoof people into visiting fake websites to induce them to give away private information, etc. So, the email services have gotten more particular about what they deem safe email in lots of different ways. If you want to do these various odd and misleading things to the emails you send out, you will have to understand how to 'beat the systems' that have been employed to stop that stuff. Having read your questions here for the last year(s) I don't believe this is an area in which you excel. You always want quick answers to questions that often show your complete lack basic understanding of the question domain. If you really want to plod along with this email spoofing, why not take a couple of weeks to read all about how email works on the internet, how email has been used to deliver viruses and spoofing schemes. After you understand that stuff well enough to show your competence in a forum where there are other email experts, as your questions there. As has been pointed out by several people here, your questions are not python language issues, they are issues relating to how email protocols work. So, study up and go to an email experts group and good luck! -- Joel Goldstick http://joelgoldstick.com --089e0111b0c2e175d504e68697ab Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable

It may however detect that your are presenting an ip and or hostname = that
does not match the host you are connecting with, and increase the spf
score on the messages to the point that the messages get rejected either in the google mta or downstream due to their spf score.
