尝试通过python发送电子邮件时出现SMTPRecipientsRefused（senderrs）错误

Question

我有一段代码，试图通过smtp发送电子邮件，但不需要登录：

import smtplib, ssl
from email.message import EmailMessage

msg = EmailMessage()
msg.set_content("The body of the email is here")
msg["Subject"] = "An Email Alert"
msg["From"] = "sender email"
msg["To"] = "fabricio.gaeta@gmail.com"

context=ssl.create_default_context()

with smtplib.SMTP("my smtp server", port=25) as smtp:
    smtp.starttls(context=context)
    smtp.connect("my smtp server,25)
    smtp.send_message(msg)

但是，我收到以下错误消息：

raise SMTPRecipientsRefused(senderrs) smtplib.SMTPRecipientsRefused: {'fabricio.gaeta@gmail.com': (554, b'5.7.1 <AP845163[10.193.8.87]>: Client host rejected: Access denied')}
