向多个地址发送电子邮件

如何在 Python 代码中向多个地址发送电子邮件？

#!/usr/bin/python

import smtplib
import sys, getopt

recipient=''
subject=''
body=''

try:
    myopts, args = getopt.getopt(sys.argv[1:],"r:s:m:")
except getopt.GetoptError as e:
    print (str(e))
    print("Usage: %s -r recipient -s subject -m message" % sys.argv[0])
    sys.exit(2)

for o, a in myopts:
    if o == '-r':
        recipient=a
    elif o == '-s':
        subject=a
    elif o == '-m':
        body=a

server = 'smtp.gmail.com'
port = 587
sender = 'foo@bar'
password = 'password'
headers = ["From: " + sender,
           "Subject: " + subject,
           "To: " + recipient,
           "MIME-Version: 1.0",
           "Content-Type: text/html"]
headers = "\r\n".join(headers)
session = smtplib.SMTP(server, port)
session.ehlo()
session.starttls()
session.ehlo
session.login(sender, password)
session.sendmail(sender, recipient, headers + "\r\n\r\n" + body)
session.quit()

准备一个字符串列表，每个字符串对应一个收件人，如下所示：

recipients = ['[email protected]', '[email protected]']
session.sendmail(sender, recipients, headers + "\r\n\r\n" + body)
