在使用 Exchange Online 中的信箱或獨立 Exchange Online (Protection 的 Microsoft 365 組織中,EOP) 不含 Exchange Online 信箱的組織,客戶有時會問:「垃圾郵件和大量電子郵件有什麼不同?」。In Microsoft 365 organizations with mailboxes in Exchange Online or standalone Exchange Online Protection (EOP) organizations without Exchange Online mailboxes, customers sometimes ask: "what's the difference between junk email and bulk email?" 本主題說明 EOP 中可用的控制項的差異和描述。This topic explains the difference and describes the controls that are available in EOP.

  • 垃圾郵件 為垃圾郵件,也就是) 正確辨識時, (未受歡迎和普遍有害的郵件。Junk email is spam, which are unsolicited and universally unwanted messages (when identified correctly). 根據預設,EOP 會根據來源電子郵件伺服器的信譽拒絕垃圾郵件。By default, the EOP rejects spam based on the reputation of the source email server. 如果郵件通過來源 IP 檢查,它會傳送至垃圾郵件篩選。If a message passes source IP inspection, it's sent to spam filtering. 如果郵件是由垃圾郵件篩選歸類為垃圾郵件,則郵件預設會 () 傳送給預定的收件者,並移至其 [垃圾郵件] 資料夾。If the message is classified as spam by spam filtering, the message is (by default) delivered to the intended recipients and moved to their Junk Email folder.

    • 您可以設定要對垃圾郵件篩選 verdicts 採取的動作。You can configure the actions to take on spam filtering verdicts. 如需相關指示,請參閱 CONFIGURE EOP 中的反垃圾郵件原則For instructions, see Configure anti-spam policies in EOP.

    • 如果您不同意垃圾郵件篩選判定,您可以使用數種方式將您認為視為垃圾郵件或非垃圾郵件的郵件,報告為 Microsoft 的 報表訊息和檔案中所述。If you disagree with the spam filtering verdict, you can report messages that you consider to be spam or non-spam to Microsoft in several ways, as described in Report messages and files to Microsoft.

  • 大量電子郵件 (也稱為 灰色郵件) ,很難進行分類。Bulk email (also known as gray mail), is more difficult to classify. 垃圾郵件是常數威脅,大量電子郵件常常是一次的廣告或行銷訊息。Whereas spam is a constant threat, bulk email is often one-time advertisements or marketing messages. 有些使用者需要大量電子郵件訊息 (,實際上,他們已特意註冊以接收) ,其他使用者則將大量電子郵件視為垃圾郵件。Some users want bulk email messages (and in fact, they have deliberately signed up to receive them), while other users consider bulk email to be spam. 例如,有些使用者想要接收來自 Contoso 公司的廣告訊息,或在網路安全性上的即將舉行的會議邀請,其他使用者請將這些相同的郵件視為垃圾郵件。For example, some users want to receive advertising messages from the Contoso Corporation or invitations to an upcoming conference on cyber security, while other users consider these same messages to be spam.

如何管理大量電子郵件How to manage bulk email

反垃圾郵件原則具有預設的 BCL 閾值,用來識別大量電子郵件為垃圾郵件。Anti-spam polices have a default BCL threshold that's used to identify bulk email as spam. 系統管理員可增加或減少閾值。Admins can increase or decrease the threshold. 如需詳細資訊,請參閱下列主題:For more information, see the following topics:

另一種易於忽視的選項:如果接收大量電子郵件的使用者 complains,但郵件是來自可透過 EOP 中垃圾郵件篩選的著名寄件者,請使用者在大量電子郵件訊息中檢查是否有 [取消訂閱] 選項。Another option that's easy to overlook: if a user complains about receiving bulk email, but the messages are from reputable senders that pass spam filtering in EOP, have the user check for a unsubscribe option in the bulk email message.
