使用PHP IMAP連接到交換服務器，交換服務器使用什麼標誌用於UNSEEN電子郵件？

Question

我使用PHP IMAP庫從Barbushin包裹在方便的小類：https://github.com/barbushin/php-imap

，我開始對我的Gmail帳戶的測試，這將迎接我的未讀郵件有以下幾點。

$imap = new IMAP(); 
$unseen = $imap->searchMailbox('UNSEEN'); 

類中的函數執行以下操作：

/* 
*  ALL - return all mails matching the rest of the criteria 
*  ANSWERED - match mails with the \\ANSWERED flag set 
*  BCC "string" - match mails with "string" in the Bcc: field 
*  BEFORE "date" - match mails with Date: before "date" 
*  BODY "string" - match mails with "string" in the body of the mail 
*  CC "string" - match mails with "string" in the Cc: field 
*  DELETED - match deleted mails 
*  FLAGGED - match mails with the \\FLAGGED (sometimes referred to as Important or Urgent) flag set 
*  FROM "string" - match mails with "string" in the From: field 
*  KEYWORD "string" - match mails with "string" as a keyword 
*  NEW - match new mails 
*  OLD - match old mails 
*  ON "date" - match mails with Date: matching "date" 
*  RECENT - match mails with the \\RECENT flag set 
*  SEEN - match mails that have been read (the \\SEEN flag is set) 
*  SINCE "date" - match mails with Date: after "date" 
*  SUBJECT "string" - match mails with "string" in the Subject: 
*  TEXT "string" - match mails with text "string" 
*  TO "string" - match mails with "string" in the To: 
*  UNANSWERED - match mails that have not been answered 
*  UNDELETED - match mails that are not deleted 
*  UNFLAGGED - match mails that are not flagged 
*  UNKEYWORD "string" - match mails that do not have the keyword "string" 
*  UNSEEN - match mails which have not been read yet 
* 
* @return array Mails ids 
*/ 
public function searchMailbox($criteria = 'ALL') { 
    $mailsIds = imap_search($this->imapStream, $criteria, SE_UID, $this->serverEncoding); 
    return $mailsIds ? $mailsIds : array(); 
} 

只是一個方便的包裝爲imap_search();http://php.net/manual/en/function.imap-search.php

在IMAP成功地連接到我的Exchange服務器，我現在可以做到以下幾點：

$imap = new IMAP(); 
$unseen = $imap->searchMailbox('ALL'); 

這將檢索所有emai在交換機上的收件箱裏（根據我的連接），我很好。

UNSEEN（如文檔所述）在Google Mail上按預期工作，但未在Exchange 2010上正常工作。ALL按預期在兩者上均可正常工作。我想知道Exchange 2010是否使用了不同的標誌？ NEW和UNREAD也不起作用。而且，我可以從這些郵件ID中獲得的返回細節不包含要從其進行反向工程的數組。

任何幫助，將不勝感激:)

如果它不工作，這是在Exchange中的錯誤。 UNSEEN搜索項對應於缺少\Seen關鍵字（消息標誌），請參閱RFC 3501, p. 52。
