使用Python实现邮件发送

如果实现一个服务器的状态通知，可以选择通过邮件提醒的方式实现。Python自带的模块库中有支持smtp协议邮件发送的功能。

写了一个简单的小例子实现Python的邮件发送功能如下：

  1 #!/usr/bin/python  

  2 # -*- coding: cp936 -*-

  3 

  4 import os, smtplib, mimetypes

  5 from email.mime.textimport MIMEText

  6 from email.mime.imageimport MIMEImage

  7 from email.mime.multipartimport MIMEMultipart

  8 

  9 mail_list = ["[e-mail]"]

 10 mail_host ="smtp.126.com"

 11 mail_user = "XXXX"

 12 mail_psswd = "XXXX"

 13 mail_psotfix = "126.com"

 14 mail_from = mail_user +"<"+mail_user + "@" + mail_psotfix +">"

 15 

 16 def send_mail(subject, content, filename =None):

 17     try:

 18         message = MIMEMultipart()

 19         message.attach(MIMEText(content))

 20         message["Subject"] = subject

 21         message["From"] = mail_from

 22         message["To"] =";".join(mail_list)

 23         if filename != Noneand os.path.exists(filename):

 24             ctype, encoding = mimetypes.guess_type(filename)

 25             if ctype isNone or encodingis notNone:

 26                 ctype ="application/octet-stream"

 27             maintype, subtype = ctype.split("/",1)

 28             attachment = MIMEImage((lambda f: (f.read(), f.close()))(open(filename,"rb"))[0], _subtype = subtype)

 29             attachment.add_header("Content-Disposition","attachment", filename = filename)

 30             message.attach(attachment)

 31 

 32         smtp = smtplib.SMTP()

 33         smtp.connect(mail_host)

 34         smtp.login(mail_user, mail_psswd)

 35         smtp.sendmail(mail_from, mail_list, message.as_string())

 36         smtp.quit()

 37 

 38         return True

 39     exceptException, errmsg:

 40        print "Send mail failed to: %s" % errmsg

 41         return False

 42 

 43 if __name__ == "__main__":

 44    if send_mail("python email title","send from python", r"筷子兄弟 - 父亲.mp3"):

 45        print "send sucess"

 46     else:

 47        print "failed to send”

send sucess

邮件发送成功，查看接收邮箱可以看到邮件已经收到。现在的唯一遗憾是附件的编码格式出了问题，成了乱码。
