email - 交易失败。服务器响应为 : 5. 2.0 STOREDRV.Submission.Exception :SendAsDeniedException. MapiExceptionSendAsDenied;

Question

有人可以帮助我解决以下问题。我们已将 smtp 更改为 office365，但在更改 smtp 主机后，我们开始遇到以下问题

交易失败。服务器响应为:5.2.0 STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied;由于消息无法提交消息的永久异常，无法处理消息。

Answer 1

SMTP 协议(protocol) ( MAIL From:<salesperson1@contoso.com> ) 中使用的电子邮件地址必须是 相同 到您的 office365 帐户名称，即“salesperson1@contoso.com”。
来源:查看此 Microsoft support页，与打印机和扫描仪相关:

"Your printer or application must send email from the same address that you entered logon credentials for during email setup. If the printer or application tries to send email from a different account, this results in an error similar to:

5.7.60 SMTP; Client does not have permissions to send as this sender.

For example, if you entered login credentials for sales@contoso.com in your application settings, but the application tries to send emails from salesperson1@contoso.com, this is not supported. For this scenario, use Microsoft 365 or Office 365 SMTP relay instead."

在我们的例子中，地址不匹配导致 office365.com 回复以下错误消息: 554 5.2.0 STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message Cannot submit message.并已如所述解决。
