Question

我收到了错误邮件：

User_One@mycompany.com
Your message wasn't delivered due to a permission or security issue. 
It may have been rejected by a moderator, the address may only accept e-mail     
from certain senders, or another restriction may be preventing delivery.

我坚持了一段时间我不知道哪里错了我尝试smtplib.SMTP('smtp.gmail.com',587)效果很好但公司smtp失败了我认为这一行是非常的：

 Received: from  localhost.localdomain (unknown [192.X.X.X])

你有什么想法吗？请帮帮我谢谢

这是代码：

def send_email(mail_from,mail_to,subject, body):
    import smtplib
    from email.mime.multipart import MIMEMultipart
    fromaddr = mail_from
    toaddr = mail_to if type(mail_to) is list else [mail_to]
    msg = MIMEMultipart()
    msg['From'] = fromaddr
    msg['To'] = ", ".join(toaddr)
    msg['Subject'] = subject
    body = body
    server = smtplib.SMTP('mail.stmpcompany.tw', 25)      
    server.set_debuglevel(True)
    server.starttls()
    text = msg.as_string()
    server.sendmail(fromaddr, toaddr, text)
    server.quit()

Answer 1

您的发件人地址（来自电子邮件中的字段）必须是您使用的邮件服务器上的现有电子邮件地址（mail.stmpcompany.tw）。

错误消息

5.7.1此系统配置为拒绝欺骗性发件人地址

当您在from字段中使用不属于为其配置邮件服务器的域的电子邮件地址或服务器也要求具有该电子邮件地址的用户实际存在时，会发生

。

你的gmail测试有效，因为googles mailserver不会检查发件人地址是否有效。
