這篇文章主要介紹了python 發(fā)送郵件的示例代碼，并且Python2/3都可以直接使用，感興趣的朋友可以參考下

發(fā)送普通郵件

發(fā)送文本和html普通郵件如下：

from email.header import Header
from email.mime.text import MIMEText
from email.utils import parseaddr, formataddr

import smtplib

def _format_addr(s):
  name, addr = parseaddr(s)
  return formataddr((Header(name, 'utf-8').encode(), addr))

def get_server(username):
  """
  通過郵箱地址獲得郵箱服務器
  :param username:用戶名，比如：123456@qq.com
  :return: 郵箱服務器地址，可以根據(jù)自己實際業(yè)務添加，比如：smtp.qq.com
  """
  servers = {'qq' : 'smtp.qq.com'
        , '126' : 'smtp.126.com'
        , '163' : 'smtp.163.com'
        , '139' : 'smtp.139.com'}

  for key,value in servers.items():
    if key in username:
      return value

def send_mail(username, password, to, sender_name, subject, content, email_type):
  """
  :param username: 
  :param password: 
  :param to: 接收者列表 []
  :param sender_name: 
  :param subject: 
  :param content: 
  :param email_type: 
  :return: 
  """
  from_addr = username
  password = password
  to_addr = to
  smtp_server = get_server(username)

  # 郵件正文是MIMEText類型
  msg = MIMEText('%s'%(content), '%s'%(email_type), 'utf-8')
  msg['From'] = _format_addr('%s<%s>' % (sender_name, from_addr))
  msg['To'] = _format_addr('<%s>' % to_addr)
  msg['Subject'] = Header('%s'%(subject), 'utf-8').encode()

  # 普通登陸端口是25，帶ssl驗證時候端口是465
  # smtp_server = 'smtp.exmail.qq.com'
  # server = smtplib.SMTP_SSL(smtp_server, 465)
  server = smtplib.SMTP(smtp_server, 25)
  server.set_debuglevel(1)
  server.login(from_addr, password)
  server.sendmail(from_addr, to_addr, msg.as_string())
  server.quit()

if __name__ == '__main__':
  """發(fā)送簡單文本郵件"""
  username = '******@126.com'
  password = '******'
  sender_name = '******@126.com'
  subject = 'test 郵件'
  content = '<html><h1>ikeguang 的來信</h1></html> <a  rel="external nofollow" >ikeguang.com</a></html>'
  # email_type 取值：plain,文本類型郵件;html,html類型郵件
  email_type = 'html'
  _to = ['******@126.com', '******@qq.com']
  for to in _to:
    send_mail(username, password, to, sender_name, subject, content, email_type)
    print('send mail to %s success' % to)

發(fā)送帶附件的郵件

def send_mail_multipart(username, password, to, sender_name, subject, content, email_type):
  from_addr = username
  password = password
  to_addr = to
  smtp_server = get_server(username)

  msg = MIMEMultipart()
  # 郵件正文是MIMEText類型
  msg.attach(MIMEText('%s'%(content), '%s'%(email_type), 'utf-8'))
  msg['From'] = _format_addr('%s<%s>' % (sender_name, from_addr))
  msg['To'] = _format_addr('<%s>' % to_addr)
  msg['Subject'] = Header('%s'%(subject), 'utf-8').encode()

  # 讀取附件
  filename = 'D:/我的文件/Codes/PyCode/source/image/0.jpg'
  with open(filename, 'rb') as f:
    # 設置附件的MIME和文件名，這里是png類型:
    mime = MIMEBase('image', 'jpg', filename='0.jpg')
    # 加上必要的頭信息:
    mime.add_header('Content-Disposition', 'attachment', filename='0.jpg')
    mime.add_header('Content-ID', '<0>')
    mime.add_header('X-Attachment-Id', '0')
    # 把附件的內(nèi)容讀進來:
    mime.set_payload(f.read())
    # 用Base64編碼:
    encoders.encode_base64(mime)
    # 添加到MIMEMultipart:
    msg.attach(mime)

  # 普通登陸端口是25，帶ssl驗證時候端口是465
  # smtplib.SMTP_SSL(smtp_server, 465)
  server = smtplib.SMTP(smtp_server, 25)
  server.set_debuglevel(1)
  server.login(from_addr, password)
  server.sendmail(from_addr, [to_addr], msg.as_string())
  server.quit()
