【python】发送邮件

从网上找了一些用python发邮件的教程，学习一下：

1、发送普通的文本邮件

抄了一份代码

import smtplib
from email.mime.text import MIMEText
mailto_list=[YYY@YYY.com]
mail_host="smtp.XXX.com"  #设置服务器
mail_user="XXXX"    #用户名
mail_pass="XXXXXX"   #口令
mail_postfix="XXX.com"  #发件箱的后缀

def send_mail(to_list,sub,content):
me="hello"+"<"+mail_user+"@"+mail_postfix+">"
msg = MIMEText(content,_subtype='plain',_charset='gb2312')
msg['Subject'] = sub
msg['From'] = me
msg['To'] = ";".join(to_list)
try:
server = smtplib.SMTP()
server.connect(mail_host)
server.login(mail_user,mail_pass)
server.sendmail(me, to_list, msg.as_string())
server.close()
return True
except Exception, e:
print str(e)
return False
if __name__ == '__main__':
if send_mail(mailto_list,"hello","hello world！"):
print "发送成功"
else:
print "发送失败"

问题：

1.用163邮箱发送，提示错误：(550, 'User has no permission')

2.用qq邮箱发送，提示错误：(530, 'Error: A secure connection is requiered(such as ssl). More information at http://service.mail.qq.com/cgi-bin/help?id=28')
3.用新浪邮箱发送，提示错误：(535, '5.7.8 authentication failed')

上面种种问题显示出了用第三方邮件服务器的不便。我的解决方法是用本机的stmp服务器发送。

首先要在本机上搭建一个stmp服务器。这一部分我没有做，直接大神帮忙解决了。

然后就很方便了，发送者的用户名随便写，也不用密码了。只要收件人的地址对了就可以了。

#coding=utf8

import smtplib
import traceback
from email.mime.text import MIMEText
mailto_list=["xxxx@xxxx"]

def send_mail(to_list,sub,content):
me="me@test.com"
msg = MIMEText(content,_subtype='plain',_charset='gb2312')
msg['Subject'] = sub
msg['From'] = me
msg['To'] = ";".join(to_list)
try:
server = smtplib.SMTP('localhost')
#server.connect(mail_host)  #不需要连接了
#server.login(mail_user,mail_pass)   #不需要登录了
server.sendmail(me, to_list, msg.as_string())
server.close()
return True
except Exception, e:
print str(e)
traceback.print_exc()
return False
if __name__ == '__main__':
if send_mail(mailto_list,"hello","hello world！"):
print "发送成功"
else:
print "发送失败"

2、以带附件的邮件，同样是本机发送的。

具体的参数原理是什么都不清楚，就从网上copy过来了。可以用。做完了有空再看原理吧。

#coding=utf8

import smtplib
import traceback
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
mailto_list=["****@****"]

def send_mail(to_list,sub,content):
me="me@test.com"
#创建一个带附件的实例
msg = MIMEMultipart()
#构造附件
att1 = MIMEText(open("/path/somefile","rb").read(), 'base64','gb2312')
att1["Content-Type"]='application/octet-stream'  #任意的二进制数据
att1["Content-Disposition"] = 'attachment; filename="somename"'#这里的filename可以任意写，写什么名字，邮件中显示什么名字
msg.attach(att1)
msg['Subject'] = sub
msg['From'] = me
msg['To'] = ";".join(to_list)
try:
server = smtplib.SMTP('localhost')
server.sendmail(me, to_list, msg.as_string())
server.close()
return True
except Exception, e:
print str(e)
traceback.print_exc()
return False
if __name__ == '__main__':
if send_mail(mailto_list,"hello","hello world！"):
print "发送成功"
else:
print "发送失败"
