case 2:添加附件:发送带附件的邮件,首先要创建MIMEMultipart()实例,然后构造附件,如果有多个附件,可依次构造,最后利用smtplib.smtp发送。

case 3: 发送图片(容易被判别为垃圾邮件,导致:SMTPDataError: (554, "DT:SPM 126……错误)

"""

import os

fp = open("test.PNG", "rb")
msgImage = MIMEImage(fp.read())
fp.close()

# 定义图片 ID,在 HTML 文本中引用
msgImage.add_header("Content-ID", "<image1>")
msgRoot.attach(msgImage)

s = smtplib.SMTP()
s.connect(smtpaddr)  #连接smtp服务器
s.login(fromaddr,password)  #登录邮箱
s.sendmail(fromaddr, toaddrs, msgRoot.as_string()) #发送邮件
s.quit()
print "邮件发送成功!"

#邮件发送成功!



       对于case3,发送很不稳定,时而发送得出,时而报 SMTPDataError: 554错误,等有空了,看有没有方法弄个稳定的版本。case1,case2在工作中基本够用了。
