python 的smtplib 的坑 554 DT:SPM 163 smtp12

我在发送邮件的时候！授权码各方面都写正确了！但是却遇到下面那个异常！

 

开始以为是传送的文本的内容有问题！被当成了是垃圾邮件不允许发送！然后改了很多次都不行！后来找了很久！才发现是From  和 To  的坑！

import smtplib
from email.mime.text import MIMEText
from email.header import Header


mail_host="smtp.163.com"
mail_user="*******.com"
mail_pass="*******"
sender = '******@163.com'
receivers = ['******@qq.com','******@163.com']
body_content = """ 测试文本  """

message = MIMEText(body_content, 'plain', 'utf-8')
message['From'] = "********@163.com"
message['To'] = "******@qq.com"
subject = """
项目异常测试邮件
"""
message['Subject'] = Header(subject, 'utf-8')
smtpObj = smtplib.SMTP()
smtpObj.connect(mail_host, 25)  
smtpObj.set_debuglevel(1)
smtpObj.login(mail_user,mail_pass)
smtpObj.sendmail(sender, receivers, message.as_string())
print("邮件发送成功")
smtpObj.quit()

这里的message['From'] 和To 改为 邮箱里收发邮件的发件人和收件人那种字符格式！

message['From'] = "wumian<**********@163.com>"
message['To'] = "qishi<**********@qq.com>"

然后就发送成功了！
