运用Python3发送邮件

 

方法一  使用自己的smtp服务器

如果想用自己的服务器作为smtp服务器，首先要执行下面的命令：

python3 -m smtpd -n -c DebuggingServer localhost:1025 &

发送邮件的代码也要做出修改

server = smtplib.SMTP(host='smtp.gmail.com', port=1025)

发送邮件的代码如下：

#!/usr/bin/python3
import smtplib
from email.mime.text import MIMEText
from email.header import Header
 
sender = '[email protected]'
receivers = ['[email protected]']  # 接收邮件，可设置为你的QQ邮箱或者其他邮箱
 
# 三个参数：第一个为文本内容，第二个 plain 设置文本格式，第三个 utf-8 设置编码
message = MIMEText('Python 邮件发送测试...', 'plain', 'utf-8')
message['From'] = Header("chen", 'utf-8')     # 发送者
message['To'] =  Header("测试", 'utf-8')          # 接收者
 
subject = 'Python SMTP 邮件测试'
message['Subject'] = Header(subject, 'utf-8')
 
 
try:
    smtpObj = smtplib.SMTP('localhost')
    smtpObj.sendmail(sender, receivers, message.as_string())
    print ("邮件发送成功")
except smtplib.SMTPException:
    print ("Error: 无法发送邮件")

 

方法二：使用第三方smtp服务器

import smtplib
from email.header import Header
from email.mime.text import MIMEText
 
# 第三方 SMTP 服务
mail_host = "smtp.163.com"   # SMTP服务器
mail_user = "[email protected]"         # 用户名
mail_pass = "xxxxx"        # 授权密码，非登录密码
 
sender = '[email protected]'  # 发件人邮箱(最好写全, 不然会失败)
receivers = ['[email protected]'] # 接收邮件，可设置为你的QQ邮箱或者其他邮箱
 
content = '你好，有你的邮件'
title = 'Python邮件' # 邮件主题
 
def sendEmail():
 
  message = MIMEText(content, 'plain', 'utf-8') # 内容, 格式, 编码
  message['From'] = "{}".format(sender)
  message['To'] = ",".join(receivers)
  message['Subject'] = title
 
  try:
    smtpObj = smtplib.SMTP_SSL(mail_host, 465) # 启用SSL发信, 端口一般是465
    smtpObj.login(mail_user, mail_pass) # 登录验证
    smtpObj.sendmail(sender, receivers, message.as_string()) # 发送
    print("mail has been send successfully.")
  except smtplib.SMTPException as e:
    print(e)
 
def send_email2(SMTP_host, from_account, from_passwd, to_account, subject, content):
  email_client = smtplib.SMTP(SMTP_host)
  email_client.login(from_account, from_passwd)
  # create msg
  msg = MIMEText(content, 'plain', 'utf-8')
  msg['Subject'] = Header(subject, 'utf-8') # subject
  msg['From'] = from_account
  msg['To'] = to_account
  email_client.sendmail(from_account, to_account, msg.as_string())
 
  email_client.quit()
 
if __name__ == '__main__':
  sendEmail()
  # receiver = '***'
  # send_email2(mail_host, mail_user, mail_pass, receiver, title, content)
