電子郵件偶爾被發送給不正確/額外的收件人

  • March 14, 2013

多年來，我們一直成功地使用 hMailServer 作為我們的郵件伺服器。最近微軟阻止了我們的垃圾郵件（即使我們有合法的選擇加入服務），所以任何 hotmail、實時電子郵件都沒有被傳遞。我們在不同的 IP 上安裝了具有相同配置的 hMailServer 的備份伺服器（我們從主伺服器導出並將其推送到備份伺服器）。但是，自從這樣做以來，我們發現了一些非常奇怪的行為，很難確定。

基本上，電子郵件會隨機發送給錯誤的收件人。這並不是一直發生的。我們還有一些包含調試資訊的電子郵件，據報導這些電子郵件已發送到客戶的電子郵件帳戶。在我們切換郵件伺服器之前，這個問題從未存在過，並且沒有更改任何程式碼。我們真的不知道是什麼導致了這種情況的發生。

由於某些資訊是敏感資訊，我們暫時不得不切換回原來的郵件伺服器，並實現一些功能，以便在將電子郵件發送到基於 microsoft 的電子郵件帳戶時，我們會收到電子郵件副本和通知，以便採取適當的措施。這顯然不是一個可行的解決方案，我們需要嘗試並準確了解正在發生的事情。

我不完全確定您想要什麼資訊，但在日誌中我們注意到一些 502（未實現的命令）。這裡有一些日誌。在下面的程式碼段中，staff-member1 和 staff-member2 根本不應該收到這些電子郵件。

我們已經在hMail 論壇上創建了一個文章，回复表明問題出在我們的程式碼中，但是我真的不明白這是怎麼可能的，因為程式碼在我們的其他郵件上執行了很多年伺服器。

抱歉，如果這有點含糊，但我們在這裡遇到了死胡同。如果您需要任何其他資訊，請詢問。

任何投入將不勝感激。

謝謝

也許以下內容可以幫助您解決問題。

看看這些字元串：

"SMTPD" 2320 14154 "2013-03-07 13:04:23.106" "IP_ADDRESS" "SENT: 354 OK, send."

"SMTPD" 2164 14154 "2013-03-07 13:04:23.278" "IP_ADDRESS" "SENT: 250 Queued (0.172 seconds)"

"APPLICATION" 2260 "2013-03-07 13:04:23.278" "SMTPDeliverer - Message 969618: Delivering message from return@email-address.co.uk to customers@email-address.co.uk, staff-member1@email-address.co.uk, c9ef15da@trustpilotservice.com, staff-member2@email-address.co.uk. File: C:\Program Files (x86)\hMailServer\Data\{1798FEFB-112E-4904-92F3-49C47683C213}.eml"

"SMTPD" 2340 14154 "2013-03-07 13:04:23.293" "IP_ADDRESS" "RECEIVED: Date: Thu, 07 Mar 2013 13:03:22 +0000"

"SMTPD" 2340 14154 "2013-03-07 13:04:23.293" "IP_ADDRESS" "SENT: 502 Unimplemented command."

電子郵件實際上是空的 -250 Queued緊接著354 OK, send.

下面的幾行250 Queued告訴您消息頭是作為 SMTP 命令傳輸的。當然，SMTP 伺服器不理解它們。

考慮調查您的程式碼。DATA 部分的結尾是 CRLF.CRLF - 載波返回（ASCII 程式碼 0xD），換行（ASCII 程式碼 0xA），點，載波返回，換行 - 可能是您的腳本或應用程序或任何錯誤地在標題之前發送它。
