python使用sendmail在linux下发送邮件

参考链接：How do I send mail from a Python script?

使用linux下的sendmail程序来发送邮件，利用popen函数（python docs关于popen函数）可以直接调用linux系统程序，需要指定程序所在的位置。

#!/usr/bin/python

SENDMAIL = "/usr/sbin/sendmail" #sendmail(可执行程序)所在的路径

sender = "sender@example.com" 
receivers = ["user1@example.com", "user2@example.com"]
subject = "这是邮件标题"
text = "这是邮件正文。"

#将这些元素组合成一条message
message = """
From: %s
To: %s
Subject: %s

%s
""" % (sender, ", ".join(receivers), subject, text)

# Send the mail
import os

p = os.popen("%s -t -i" % SENDMAIL, "w")
p.write(message)
status = p.close()
if status:
    print "Sendmail exit status", status
