SMTP 验证错误：用户名和密码不被接受：

Question

我的电子邮件和密码正确，但我无法使用我的脚本发送电子邮件。

import smtplib
content ="hello"
mail = smtplib.SMTP("smtp.gmail.com",587)
mail.ehlo()
mail.starttls()
mail.login('[email protected]','password')
mail.sendmail('[email protected]','[email protected]',content)
mail.close()

我遇到了和你一样的问题，但我找到了这篇文章，我可以解决它：smtp错误：535 5.7.8 Go中的gmail不接受用户名和密码

您必须在 myaccount.google.com/security 中启用 2FA

（如你所见，实际上我已经激活了它）

然后您需要来这里创建一个新应用程序：https://security.google.com/settings/security/apppasswords

现在，它会给您带来一个类似 XXXX XXXX XXXX 的代码，您必须使用该代码而不是您的实际密码

import smtplib
from email.mime.text import MIMEText

# Configuration
port = 465 #465 for SSL | 587 for TTL
smtp_server = "smtp.gmail.com"
sender_mail = "<[email protected]>"

password = "XXXX XXXX XXXX XXXX"  #App code generated by google

receiver_email = ", ".join([<[email protected]>, ...])

# Plain text content
text = """\
Hello world
"""

# Create MIMEText object
message = MIMEText(text, "plain")
message["Subject"] = "Plain text email"
message["From"] = sender_email
message["To"] = receiver_email

# Send the email (VIA SSL) port = 465
with smtplib.SMTP_SSL(smtp_server, port) as server:
    server.ehlo()
    server.login(sender_email, password)
    server.sendmail(sender_email, receiver_email, message.as_string())

# Send the email (VIA TTL) port = 587
with smtplib.SMTP(smtp_server, port) as server:
    server.ehlo()
    server.starttls()  # Secure the connection
    server.login(sender_email, password)
    server.sendmail(sender_email, receiver_email, message.as_string())

print('Sent')

希望它可以帮助您或其他人:)

Answer 2

您的凭据前后需要一个空格，如下所示：

mail.login(' [email protected] ',' password ')
mail.sendmail(' [email protected] ',' [email protected] ',content)

然后就可以了。

完整的代码示例，在我的程序中运行：

emailpassword = ' password ' 
emailsend = ' [email protected] '
emailreceive = ' [email protected] '

import smtplib
smtpObj = smtplib.SMTP('smtp.gmail.com', 587)
type(smtpObj)
smtpObj.ehlo()
smtpObj.starttls()
smtpObj.login(' [email protected] ', emailpassword)
smtpObj.sendmail(emailsend, emailreceive, 'Subject: test\nThis is an automated email.')
smtpObj.quit()
