转：Python发送Email(1）

Python对于Email的分成两个部分：

1. 对于POP、SMTP的支持。
2. 对于Email数据的支持。

第一部分：
用POP、SMTP来读取信件：

import getpass, poplib

M = poplib.POP3('localhost')
M.user(getpass.getuser())
M.pass_(getpass.getpass())
numMessages = len(M.list()[1])
for i in range(numMessages):
for j in M.retr(i+1)[1]:
第二部分，对于数据的支持：

• 发送普通文本类型邮件：

  # Import smtplib for the actual sending function
  import smtplib
  
  # Import theemailmodules we'll need
  fromemail.mime.text import MIMEText
  
  # Open a plain text file for reading.  For this example, assume that
  # the text file contains only ASCII characters.
  fp = open(textfile, 'rb')
  # Create a text/plain message
  msg = MIMEText(fp.read())
  fp.close()
  
  # me == the sender'semailaddress
  # you == the recipient'semailaddress
  msg['Subject'] = 'The contents of %s' % textfile
  msg['From'] = me
  msg['To'] = you
  
  # Send the message via our own SMTP server, but don't include the
  # envelope header.
  s = smtplib.SMTP()
  s.connect()
  s.sendmail(me, [you], msg.as_string())
  s.close()
  

• 发送带有图片附件的邮件：

import smtplib
# 需要导入的Module
fromemail.mime.image import MIMEImage
fromemail.mime.multipart import MIMEMultipart
COMMASPACE = ', '
# 生成需要的Object
emailmessage. msg = MIMEMultipart()
msg['Subject'] = 'Our family reunion'
# me ==源地址
# family = 需要发送的地址
msg['From'] = me
msg['To'] = COMMASPACE.join(family)
msg.preamble = 'Our family reunion'
#pngfiles是一些图形的文件名列表
for file in pngfiles:
# 打开文件
# 自动探测图形类型
fp = open(file, 'rb')
img = MIMEImage(fp.read())
fp.close()
msg.attach(img)
# 通过SMTP发送
s = smtplib.SMTP()
s.connect()
s.sendmail(me, family, msg.as_string())
s.close()

比较简单，明天继续
