使用 python smtplib 发送邮件错误

2022-01-17 00:00:00 python email smtp python-3.2 yahoo-mail

问题描述

我正在尝试使用 python 3.2 SMTPlib.sendmail() 函数发送消息，经过 SMTP 库的一些修改(即注释掉抑制错误消息的 rset() 函数)我设法从服务器检索到以下错误消息:

I am attempting to use the python 3.2 SMTPlib.sendmail() function to send a message, after some modifcation of the SMTP library (namely commenting out the rset() function which was suppressing the error msg) I managed to retrieve the following error message from the server:

发送邮件失败(554, b'Transaction failed : 由于可能滥用，无法发送消息；请访问 http://postmaster.yahoo.com/abuse_smtp.html 了解更多信息')

SendMail Failed (554, b'Transaction failed : Cannot send message due to possible abuse; please visit http://postmaster.yahoo.com/abuse_smtp.html for more information')

雅虎邮件 SMTP 服务器认为我在发送垃圾邮件，该 URL 确实链接到任何内容有用.我认为这与标题不足有关，我似乎无法找到明确的回答什么构成合规标头和我读过 Gmail 的类似问题.此帖子已替换为模拟电子邮件.

The yahoo mail SMTP server thinks I'm sending spam, the URL does link to anything useful. I think it has to do with an inadequate header, I can't seem to find a definitive answer on what constitutes a compliant header & I've read of simmilar issues with Gmail. Mock emails have been substituted for this post.

任何帮助将不胜感激

我的完整代码如下:

    self.message =  email.message_from_string('''To: <ksmith@yahoo.co.nz>
    From: <rwilson@yahoo.co.nz>
    Reply-To: <rwilson@yahoo.co.nz>
    Subject: Test send mail 

 Hello''')
    fromAddress = 'rwilson@yahoo.co.nz'
    toAddress = 'ksmith@yahoo.co.nz'
    try:
        self.smtp = SMTP()
        self.smtp.connect('smtp.mail.yahoo.com')
    except Exception:
        print('Connection Failed')
        print(traceback.format_exc())
    try:
        self.smtp.login('rwilson','tree22')
    except Exception:
        print('Login Failed!')
        print(traceback.format_exc())
    try:
        self.smtp.sendmail(fromAddress,toAddress ,self.message.as_string())
        print("Message sucessfully sent!")
        self.smtp.close()
    except Exception as e:
        print('SendMail Failed')
        print(e)

解决方案

以下适用于 Python 2.7 和 Python 3.2 上的 microsoft、google、yahoo 帐户:

The following works for microsoft, google, yahoo accounts on Python 2.7 and Python 3.2:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
"""Send email via smtp_host."""
import smtplib
from email.mime.text import MIMEText
from email.header    import Header

####smtp_host = 'smtp.live.com'        # microsoft
####smtp_host = 'smtp.gmail.com'       # google
smtp_host = 'smtp.mail.yahoo.com'  # yahoo
login, password = ...
recipients_emails = [login]

msg = MIMEText('body…', 'plain', 'utf-8')
msg['Subject'] = Header('subject…', 'utf-8')
msg['From'] = login
msg['To'] = ", ".join(recipients_emails)

s = smtplib.SMTP(smtp_host, 587, timeout=10)
s.set_debuglevel(1)
try:
    s.starttls()
    s.login(login, password)
    s.sendmail(msg['From'], recipients_emails, msg.as_string())
finally:
    s.quit()
