How to send mail with To, CC and BCC?

I need to populate a few hundred email boxes with various messages for testing purposes and I was going to use smtplib for that. I need to send messages not only To specific mailboxes, but CC and BCC them as well. How do I do that?
Email headers don't matter to the SMTP server. Just add CC and BCC recipients to to_addrs when sending emails. For CC, add them to the CC header. toaddr = 'buffy@sunnydale.k12.ca.us' cc = ['alexander@sunydale.k12.ca.us','willow@sunnydale.k12.ca.us'] bcc = ['chairman@slayerscouncil.uk'] fromaddr = 'giles@sunnydale.k12.ca.us' message_subject = "disturbance in sector 7" message_text = "Three are dead in an attack in the sewers below sector 7." message = "From: %s\r\n" % fromaddr + "To: %s\r\n" % toaddr + "CC: %s\r\n" % ",".join(cc) + "Subject: %s\r\n" % message_subject + "\r\n" + message_text toaddrs = [toaddr] + cc + bcc server = smtplib.SMTP('smtp.sunnydale.k12.ca.us') server.set_debuglevel(1) server.sendmail(fromaddr, toaddrs, message) server.quit()
