发送普通邮件

发送文本和html普通邮件如下：

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):
"""
通过邮箱地址获得邮箱服务器
:param username:用户名，比如：123456@qq.com
:return: 邮箱服务器地址，可以根据自己实际业务添加，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)

# 邮件正文是MIMEText类型
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()

# 普通登陆端口是25，带ssl验证时候端口是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__':
"""发送简单文本邮件"""
username = '******@126.com'
password = '******'
sender_name = '******@126.com'
subject = 'test 邮件'
content = '<html><h1>ikeguang 的来信</h1></html> <a href="http://www.ikeguang.com" rel="external nofollow" >ikeguang.com</a></html>'
# email_type 取值：plain,文本类型邮件;html,html类型邮件
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)

发送带附件的邮件

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()
# 邮件正文是MIMEText类型
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()

# 读取附件
filename = 'D:/我的文件/Codes/PyCode/source/image/0.jpg'
with open(filename, 'rb') as f:
# 设置附件的MIME和文件名，这里是png类型:
mime = MIMEBase('image', 'jpg', filename='0.jpg')
# 加上必要的头信息:
mime.add_header('Content-Disposition', 'attachment', filename='0.jpg')
mime.add_header('Content-ID', '<0>')
mime.add_header('X-Attachment-Id', '0')
# 把附件的内容读进来:
mime.set_payload(f.read())
# 用Base64编码:
encoders.encode_base64(mime)
# 添加到MIMEMultipart:
msg.attach(mime)

# 普通登陆端口是25，带ssl验证时候端口是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()
