在具有 Exchange Online 邮箱的 Microsoft 365 组织中或没有 Exchange Online 邮箱的独立 Exchange Online Protection (EOP) 组织中,EOP 使用反垃圾邮件策略 (也称为垃圾邮件筛选器策略或内容筛选器策略) 扫描入站邮件中的垃圾邮件。In Microsoft 365 organizations with mailboxes in Exchange Online or standalone Exchange Online Protection (EOP) organizations without Exchange Online mailboxes, EOP uses anti-spam policies (also known as spam filter policies or content filter policies) to scan inbound messages for spam. 有关详细信息,请参阅在 EOP 中配置反垃圾邮件策略For more information, see Configure anti-spam policies in EOP.

如果您希望在垃圾邮件筛选扫描特定邮件之前将其标记为垃圾邮件,或将邮件标记为跳过垃圾邮件筛选,您可以创建邮件流规则 (也称为传输规则) 以标识邮件,并设置垃圾邮件可信度 (SCL) 。If you want to mark specific messages as spam before they're even scanned by spam filtering, or mark messages so they'll skip spam filtering, you can create mail flow rules (also known as transport rules) to identify the messages and set the spam confidence level (SCL). 有关 SCL 详细信息,请参阅 EOP中的垃圾邮件 (SCL) 级别。For more information about the SCL, see Spam confidence level (SCL) in EOP.

开始前,有必要了解什么?What do you need to know before you begin?

使用 EAC 创建设置邮件 SCL 的邮件流规则Use the EAC to create a mail flow rule that sets the SCL of a message

  1. In the EAC, go to Mail flow > Rules.In the EAC, go to Mail flow > Rules.

  2. 单击 添加  添加图标 ,然后选择 创建新规则Click Add Add icon and then select Create a new rule.

  3. 在打开的" 新规则"窗口中,配置以下设置:In the New rule page that opens, configure the following settings:

    • 名称:输入规则的唯一描述性名称。Name: Enter a unique, descriptive name for the rule.

    • 单击“其他选项”。Click More Options.

    • 在 以下情况下应用此规则:选择一个或多个条件来标识邮件。Apply this rule if: Select one or more conditions to identify messages. 有关详细信息,请参阅 Mail flow rule conditions and exceptions (predicates) in Exchange OnlineFor more information, see Mail flow rule conditions and exceptions (predicates) in Exchange Online.

    • 执行以下操作:选择****"修改邮件属性 > "设置 SCL (垃圾邮件可信度) 。Do the following: Select Modify the message properties > set the spam confidence level (SCL). 在出现的 "指定 SCL" 对话框中,配置下列值之一:In the Specify SCL dialog that appears, configure one of the following values:

    • 绕过垃圾邮件筛选:邮件将跳过垃圾邮件筛选。Bypass spam filtering: The messages will skip spam filtering.

      注意

      请谨慎允许邮件跳过垃圾邮件筛选。Be very careful about allowing messages to skip spam filtering. 攻击者可以使用此漏洞向组织发送网络钓鱼邮件和其他恶意邮件。Attackers can use this vulnerability to send phishing and other malicious messages into your organization. 邮件流规则需要的不仅仅是发件人的电子邮件地址或域。The mail flow rules requires more than just the sender's email address or domain. 有关详细信息,请参阅在 EOP 中创建安全发件人列表For more information, see Create safe sender lists in EOP.

    • 0 到 4: 邮件通过垃圾邮件筛选进行其他处理。0 to 4: The message is sent through spam filtering for additional processing.

    • 5 或 6: 邮件被标记为"垃圾邮件 "。5 or 6: The message is marked as Spam. 为反垃圾邮件策略中的垃圾邮件筛选裁定配置的操作将应用于邮件 (默认值为"将邮件移动到垃圾邮件文件夹") 。 The action that you've configured for Spam filtering verdicts in your anti-spam policies is applied to the message (the default value is Move message to Junk Email folder).

    • 7 到 9: 邮件被标记为 高可信度垃圾邮件7 to 9: The message is marked as High confidence spam. 为反垃圾邮件策略中的高可信度垃圾邮件筛选裁定配置的操作将应用于邮件 (默认值为"将邮件移动到垃圾邮件文件夹") 。 The action that you've configured for High confidence spam filtering verdicts in your anti-spam policies is applied to the message (the default value is Move message to Junk Email folder).

  4. 指定规则需要的任何附加属性。Specify any additional properties that you want for the rule. 完成后,单击“保存”。When you're finished, click Save.

您如何知道操作成功?How do you know this worked?

要验证此步骤是否能正常工作,请发送电子邮件至组织中的某位同事,并验证是否对该邮件执行预期的操作。To verify that this procedure is working correctly, send an email message to someone inside your organization, and verify that the action performed on the message is as expected. 例如,如果将垃圾邮件可信度设置为 (SCL ) "绕过 垃圾邮件筛选",则邮件应发送到指定收件人的收件箱。For example, if you set the spam confidence level (SCL) to Bypass spam filtering, then the message should be sent to the specified recipient's inbox. 但是,如果将垃圾邮件可信度 (SCL) 设置为 9, 并且适用反垃圾邮件策略的高可信度垃圾邮件操作是将邮件移动到"垃圾邮件"文件夹,则邮件应发送到指定收件人的"垃圾邮件"文件夹。However, if you set the spam confidence level (SCL) to 9, and the High confidence spam action for your applicable anti-spam policies is to move the message to the Junk Email folder, then the message should be sent to the specified recipient's Junk Email folder.
