启用自动死邮件处理

当路由器无法将邮件传送或传输给预期收件人或无法将未送达报告传送给发件人时，就会出现死邮件。您可以将路由器配置为自动重试无效邮件的传递，如果在指定的重试尝试次数后不成功，则将其从mail.box中删除。

关于这个任务

当您启用死邮件处理并且路由器在mail.box中检测到死邮件时，会发生以下步骤：
  1. 如果已达到允许的传递尝试次数，路由器将删除无效消息并结束处理。如果管理员已将允许的传递尝试设置为 0，则失效邮件将被删除，而无需重试传递。
  2. 路由器尝试将原始消息传送给接收者。如果成功，处理结束。
    注意：当目标收件人来自公司外部的外部域时，将跳过步骤 2。
  3. The router attempts to deliver a non-delivery report to the sender. If successful, processing ends.
  4. The router waits the specified retry interval then begins with step 1 again.
Note: This feature might not be compatible with third party extensions that depend on holding dead mail until some specified processing occurs.

Complete the following steps to configure dead mail processing on Domino® mail servers.

Procedure

  1. Open the Domino® directory.
  2. Expand Configuration > Servers > Configurations.
  3. If a Configurations document associated with the mail server exists, click Edit Configuration. Otherwise, click Add Configuration to create one.
  4. Select Router/SMTP > Advanced > Controls.
  5. In the section Undeliverable Mail, in the field Automatically process dead mail, select Enabled.
  6. In the field Dead mail delivery attempts allowed, enter the number of times to allow the router to try to deliver dead mail before deleting it. (Default is 12, maximum is 1000.) The count is maintained across router and server restarts. If you enter 0, there is no delivery retry attempt and dead mail is deleted.
  7. In the field Time between dead mail delivery attempts, enter the number of minutes between delivery attempts. Default is 360 (6 hours), minimum is 15, and maximum is 1440 (24 hours).
  8. If there are mail servers in more than one internet domain within your company, in the field Internal internet domains, specify each internet domain to retry delivery to, separated by commas. Leave blank if there's only one internet domain at your company. For example: 
    renovations.com,renovations2.com

    A server retries resending an original message if the non-delivery report came from one of these internal domains. Non-delivery reports from domains not listed here are assumed to be from external domains; in this case the router attempts only to resend the non-delivery report to the sender and not the original message.
