【问题描述】：

我尝试使用下面的亚马逊 SES API 文档发送电子邮件，python 返回代码 250 表示正常，但我的电子邮件收到一条失败消息。谁能告诉我可能是什么问题？谢谢

蟒蛇：

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

# https://us-east-2.console.aws.amazon.com/sesv2/home?region=us-east-2#/account
# https://console.aws.amazon.com/iam/home?#/s=SESHomeV4/us-east-2
mail_host = "email-smtp.us-east-2.amazonaws.com"
mail_user = "AKI....T7H"
mail_pass = "BHJ.....iS/x"

sender = 'thelou1s@...com'
receivers = 'thelou1s@...com'

msg = MIMEMultipart()
msg['From'] = sender
msg['To'] = receivers
msg['Subject'] = 'simple email in python'
message = 'here is the email'
msg.attach(MIMEText(message))

try:
    print("try smtplib.SMTP")
    smtp = smtplib.SMTP(mail_host, 587)
    smtp.set_debuglevel(True)

    print("try connect")
    smtp.ehlo()
    smtp.starttls()
    smtp.ehlo()
    # smtpObj.connect(mail_host, 465)

    print("try login")
    smtp.login(mail_user, mail_pass)
    print("try sendmail: " + msg.as_string())
    smtp.sendmail(sender, receivers, msg.as_string())
    print("Send Success")
    smtp.close()
except smtplib.SMTPException:
    print("Send Error")

log（retcode 250是代码端成功还是用户端成功？）：

reply: retcode (250); Msg: b'Ok 010f017d8f0f1703-d018f2a9-833e-428e-9010-5e45818e51e4-000000'
data: (250, b'Ok 010f017d8f0f1703-d018f2a9-833e-428e-9010-5e45818e51e4-000000')
Send Success

来自亚马逊的电子邮件：

Delivery Status Notification (Failure)
An error occurred while trying to deliver the mail to the following recipients:
thelou1s@...com
here is the email

【问题讨论】：

您好像成功将邮件发送到服务器，但服务器无法投递给收件人。
当您收到250 OK 时，消息从aws 发出，他们已成功发送您的消息。现在取决于 recipeint 的服务器如何处理电子邮件。

只需在亚马逊控制台中验证您的电子邮件
