python：如何用TO，CC和BCC發送郵件？

Question

我需要測試的目的是用各種消息來填充幾百個電子郵箱，並且會爲此使用smtplib。但除此之外，我需要能夠不僅發送郵件到特定的郵箱，而且CC和BCC也是如此。它看起來不像 smtplib在發送電子郵件時支持CC-ing和BCC-ing。

尋找建議如何執行CC或BCC從python腳本發送消息。

（和 - 不，我不是在我的測試環境之外創建一個腳本，以垃圾郵件的人。）

Answer 1

電子郵件標題別無論對於SMTP服務器。發送電子郵件時，只需將CC和BCC收件人添加到toaddrs即可。對於CC，將它們添加到CC標頭。

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() 

Answer 2

TO，CC之間的區別和BCC只有在文本標題出現。在SMTP級別，每個人都是收件人。

TO - 有一個TO：本收件人的地址

CC頭 - 有一個CC：本收件人的地址

BCC頭 - 這方未在標題中提到的所有，但仍是收件人。

如果你有

TO: abc@company.com 
CC: xyz@company.com 
BCC: boss@company.com 

你有三個收件人。在電子郵件正文的標題將只包括TO：和CC：

Answer 3

您可以嘗試MimeText用於

msg = MIMEText('text') 
msg['to'] = 
msg['cc'] = 

然後發送msg.as_string（）

Answer 4

請勿添加密件抄送標題。

看到這個：http://mail.python.org/pipermail/email-sig/2004-September/000151.html

而且這樣的：「」「注意，第二個參數sendmail的（），收件人，作爲一個列表被傳遞您可以在列表中的任何數量的地址有。消息通過包括他們在法的說法，但沒有在郵件標題中依次傳遞給每個人。由於包絡信息從郵件頭分開的，你甚至可以BCC的人。「」」從http://pymotw.com/2/smtplib

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) 
    # don't add this, otherwise "to and cc" receivers will know who are the bcc receivers 
    # + "BCC: %s\r\n" % ",".join(bcc) 
    + "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() 

Answer 5

關鍵是將收件人添加爲電子郵件ID列表在你的sendmail調用中。

import smtplib 
from email.mime.multipart import MIMEMultipart 

me = "user63503@gmail.com" 
to = "someone@gmail.com" 
cc = "anotherperson@gmail.com,someone@yahoo.com" 
bcc = "bccperson1@gmail.com,bccperson2@yahoo.com" 

rcpt = cc.split(",") + bcc.split(",") + [to] 
msg = MIMEMultipart('alternative') 
msg['Subject'] = "my subject" 
msg['To'] = to 
msg['Cc'] = cc 
msg['Bcc'] = bcc 
msg.attach(my_msg_body) 
server = smtplib.SMTP("localhost") # or your smtp server 
server.sendmail(me, rcpt, msg.as_string()) 
server.quit() 

Answer 6

，直到我創造它沒有爲我工作：

#created cc string 
cc = ""someone@domain.com; 
#added cc to header 
msg['Cc'] = cc 

，比收件人[名單]新增CC這樣的：

s.sendmail(me, [you,cc], msg.as_string())
