本文实例讲述了Python发送邮件功能。分享给大家供大家参考，具体如下：

这里以QQ邮箱为例说明

登录邮箱点账号

开启smtp

开启时会要求你发送一条短信，发送完成后点已发送。

就有授权码了

代码如下，只需更改发件人、收件人等信息即可

# encoding: utf-8

import logging

import smtplib

from email.mime.text import MIMEText

import email.utils

from datetime import datetime

_logger = logging.getLogger('utils.mailclient')

class MailClient(object):

def __init__(self, host, port, user, pwd=''):

self._host = host

self._port = port

self._user = user

self._pwd = pwd

self._smtp_server = None

self._debug = False

self._keepalive = True

def set_keepalive(self, keepalive):

self._keepalive = keepalive

def set_debug(self, debug):

self._debug = debug

if self._smtp_server is not None:

self._smtp_server.set_debuglevel(self._debug)

def _connect(self):

if self._smtp_server is None:

_smtp_server = smtplib.SMTP(self._host, self._port)

_smtp_server.ehlo()

_smtp_server.starttls()

_smtp_server.set_debuglevel(self._debug)

if self._pwd:

_smtp_server.login(self._user, self._pwd)

self._smtp_server = _smtp_server

return self._smtp_server

def _dispose(self):

if self._smtp_server is not None:

self._smtp_server.quit()

self._smtp_server = None

def send(self, to_addrs, subject, content, isdispose=True):

_smtp_server = self._connect()

if not isinstance(to_addrs, list):

to_addrs = [to_addrs]

_msg = MIMEText(content, 'html', 'utf-8')

_msg['Subject'] = subject

_msg['From'] = self._user

_msg['To'] = '; '.join(to_addrs)

_msg['Date'] = datetime.now().strftime('%Y-%d-%m %H:%M:%S')

_smtp_server.sendmail(self._user, to_addrs, _msg.as_string())

isdispose and (not self._keepalive) and self._dispose()

def send_mails(self, mails):

_smtp_server = self._connect()

for mail in mails:

self._send_mail(mail.get('to'), mail.get('subject'), mail.get('content'), False)

(not self._keepalive) and self._dispose()

def close(self):

self._dispose()

if __name__ == '__main__':

logging.basicConfig(level=logging.DEBUG,

format='%(asctime)s %(name)s %(levelname)s:%(message)s',

datefmt='%Y-%m-%d %H:%M:%S')

import time

s = MailClient('smtp.qq.com', 587, '10010@qq.com', '授权码') # 注意，此处端口要用587,465端口是ssl使用的。

s.set_keepalive(False)

s.set_debug(True)

st = time.time()

s.send('收信人邮箱地址', '测试', '测试邮件 From QQ') #要发送的账号、标题、内容

print(time.time() - st)

希望本文所述对大家Python程序设计有所帮助。
