python：从本地主机发送邮件没有按预期工作

Question

我试图从localhost发送消息：1025。我使用这个命令python -m smtpd -n localhost:1025运行一个smtp调试服务器。

下面是用于发送邮件代码：

msg = mailer.Message(From='noreply@'+company['host'], 
         To=req['mail'], 
         Subject='E-mail confirmation', 
Body=Template(open('./confirmation.html').read()).render(company=company, account=account, accode=accode)) 
mailer.Mailer(company['host'], port=1025).send(msg) 

的REQ [“邮件”]是包含我的电子邮件地址，当我检查我的电子邮件收件箱和垃圾邮件文件夹，我没有发现任何消息 - 什么应该导致这个问题？

Answer 1

我认为使用smtpd /邮件是一个错误。

1. 测试进出口使用：

   nano testexim

   From: "Exim" <noreply@localhost> 
   To: MYFULLNAME MYEMAILADDRESS 
   Reply-To: noreply@localhost 
   Subject: Hello exim! 
   Content-Type: text/plain; charset=utf-8 
   
   this is exim test message 
   
   EOF 
   

   sendmail MYEMAILADDRESS < testexim

   结果：该消息得到了顺利通过进出口发送（sendmail命令）

2. Tested smtpd using:

   我用这个方法解决了这个问题

   python

   import smtplib 
   Import email.utils 
   from email.mime.text import MIMEText 
   
   # Create the message 
   msg = MIMEText('Hello SMTPD!') 
   msg['To'] = email.utils.formataddr((MYFULLNAME, 
               MYEMAILADDRESS)) 
   msg['From'] = email.utils.formataddr(('SMTPD', 
               'noreply@localhost')) 
   msg['Subject'] = 'SMTPD test message' 
   
   server = smtplib.SMTP('localhost', 1025) 
   server.set_debuglevel(True) # show communication with the server 
   try: 
       server.sendmail('noreply@localhost', 
           [MYEMAILADDRESSS], 
           msg.as_string()) 
   finally: 
       server.quit() 
   

   结果：通过smtpd的将消息发送失败

3. Tried a method not based on smtpd:

   python

   from email.mime.text import MIMEText 
   from subprocess import Popen, PIPE 
   
   msg = MIMEText("Hello from exim") 
   msg["From"] = "noreply@localhost" 
   msg["To"] = MYEMAILADDRESS 
   msg["Subject"] = "Python sendmail test" 
   p = Popen(["/usr/sbin/sendmail", "-t", "-oi"], stdin=PIPE) 
   p.communicate(msg.as_string()) 
   

   结果：创建一个sendmail进程编程做的工作

作为非常明确in the documentation调试服务器不会尝试传递电子邮件。这是为了在不实际发送任何邮件的情况下测试和验证电子邮件的内容。
