  if send_mail(mailto_list, sub, content):
    print "發(fā)送成功"

2.郵件正文是表格的格式：由于是表格，所以我們選擇HTML來實(shí)現(xiàn)表格的功能，郵件上面顯示的就是HTML實(shí)現(xiàn)的內(nèi)容了。

from email.mime.text import MIMEText
import smtplib
import sys
import csv
import xlrd
from pyExcelerator import *
import os
import xlwt
from xlutils.copy import copy
import pyExcelerator
import datetime
import time

reload(sys)
sys.setdefaultencoding("utf-8")

mailto_list = [""] # 郵件接收方的郵件地址
mail_host = "smtp.exmail.qq.com"  # 郵件傳送協(xié)議服務(wù)器
mail_user = "" # 郵件發(fā)送方的郵箱賬號(hào)
mail_pass = "" # 郵件發(fā)送方的郵箱密碼

def send_mail(to_list, sub, content):
  me = "天才白癡夢"+"<"+mail_user+">"
  # 和上面的代碼不同的就是，這里我們選擇的是html 的格式
  msg = MIMEText(content, _subtype='html', _charset='utf-8')
  msg['Subject'] = sub  # 郵件主題
  msg['From'] = me
  msg['To'] = ";".join(to_list)
  try:
    server = smtplib.SMTP()
    server.connect(mail_host)
    server.login(mail_user, mail_pass)
    server.sendmail(me, to_list, msg.as_string())
    server.close()
    return True
  except Exception, e:
    print str(e)
    return False

if __name__ == '__main__':
  sub = "天才白癡夢"
  html = '<html></html>'
  if send_mail(mailto_list, sub, html):
    print "發(fā)送成功"
  else:
    print "發(fā)送失敗"

3.郵件正文是圖片的格式：要把圖片嵌入到郵件正文中，我們只需按照發(fā)送附件的方式，先把郵件作為附件添加進(jìn)去，然后，在HTML中通過引用src="cid:0"就可以把附件作為圖片嵌入了。如果有多個(gè)圖片，給它們依次編號(hào)，然后引用不同的cid:x即可。

def send_mail(to_list, sub, content):
  me = "天才白癡夢"+"<"+mail_user+">"

  msg = MIMEMultipart()
  msg['Subject'] = sub  # 郵件主題
  msg['From'] = me
  msg['To'] = ";".join(to_list)

  txt = MIMEText("天才白癡夢", _subtype='plain', _charset='utf8')
  msg.attach(txt)

  # <b>：黑體 <i>：斜體
  msgText = MIMEText('<b>Some <i>HTML</i> text</b> and an image.<img alt="" src="cid:image1" />good!', 'html', 'utf-8')
  msg.attach(msgText)

  file1 = "F:\\1.jpg"
  image = MIMEImage(open(file1, 'rb').read())
  image.add_header('Content-ID', '<image1>')
  msg.attach(image)

  try:
    server = smtplib.SMTP()
    server.connect(mail_host)
    server.login(mail_user, mail_pass)
    server.sendmail(me, to_list, msg.as_string())
    server.close()
    return True
  except Exception, e:
    print str(e)
    return False

if __name__ == '__main__':
  sub = "天才白癡夢"
  html = '<html></html>'
  if send_mail(mailto_list, sub, html):
    print "發(fā)送成功"
  else:
    print "發(fā)送失敗"

4.發(fā)送郵件附件：郵件附件是圖片

def send_mail(to_list, sub, content):
  me = "天才白癡夢"+"<"+mail_user+">"

  msg = MIMEMultipart()
  msg['Subject'] = sub  # 郵件主題
  msg['From'] = me
  msg['To'] = ";".join(to_list)

  txt = MIMEText("天才白癡夢", _subtype='plain', _charset='utf8')
  msg.attach(txt)

  # # <b>：黑體 <i>：斜體
  # msgText = MIMEText('<b>Some <i>HTML</i> text</b> and an image.<img alt="" src="cid:image1" />good!', 'html', 'utf-8')
  # msg.attach(msgText)
  #
  # file1 = "F:\\1.jpg"
  # image = MIMEImage(open(file1, 'rb').read())
  # image.add_header('Content-ID', '<image1>')
  # msg.attach(image)

  att = MIMEText(open('F:\\1.jpg', 'rb').read(), 'base64', 'utf-8')
  att["Content-Type"] = 'application/octet-stream'
  att["Content-Disposition"] = 'attachment; filename="1.jpg"'
  msg.attach(att)

  try:
    server = smtplib.SMTP()
    server.connect(mail_host)
    server.login(mail_user, mail_pass)
    server.sendmail(me, to_list, msg.as_string())
    server.close()
    return True
  except Exception, e:
    print str(e)
    return False

5.發(fā)送群郵件：同時(shí)發(fā)送給多人
mailto_list = [""] # 郵件接收方的郵件地址
上面這一行代碼是郵件接收方的郵件地址，如果我們需要給多人發(fā)送郵件的話，就只需要把對(duì)方的郵件帳號(hào)綁在這一個(gè)列表里就ok了。

加密SMTP

使用標(biāo)準(zhǔn)的25端口連接SMTP服務(wù)器時(shí)，使用的是明文傳輸，發(fā)送郵件的整個(gè)過程可能會(huì)被竊聽。要更安全地發(fā)送郵件，可以加密SMTP會(huì)話，實(shí)際上就是先創(chuàng)建SSL安全連接，然后再使用SMTP協(xié)議發(fā)送郵件。

方法：只需要在創(chuàng)建SMTP對(duì)象后，立刻調(diào)用starttls()方法，就創(chuàng)建了安全連接。

smtp_server = 'smtp.qq.com'
smtp_port = 25  # 默認(rèn)端口號(hào)為25
server = smtplib.SMTP(smtp_server, smtp_port)
server.starttls()
# 剩下的代碼和前面的一模一樣:
server.set_debuglevel(1)   # 打印出和SMTP服務(wù)器交互的所有信息

以上就是關(guān)于Python發(fā)送郵件詳細(xì)解析，希望對(duì)大家的學(xué)習(xí)有所幫助。
