IMAP電子郵件通道適配器拋出異常「A5 BAD無效的命令或參數;」

我使用IMAP空閒通道適配器來接收春季整合電子郵件：IMAP電子郵件通道適配器拋出異常「A5 BAD無效的命令或參數;」

A5 SEARCH NOT (ANSWERED) NOT (DELETED) NOT (SEEN) NOT (FLAGGED) ALL 
A5 BAD invalid command or parameters

似乎上面的IMAP服務器方面的命令無效，誰能告訴我如何解決？

我調試消息：

我的配置

<int-mail:imap-idle-channel-adapter id="mailAdapter" 
            store-uri="imaps://${username}:${password}@imap.mxhichina.com/INBOX" 
            channel="inboundChannel" 
            auto-startup="true" 
            should-delete-messages="true" 
            should-mark-messages-as-read="true" 
            java-mail-properties="javaMailProperties"/> 

    <util:properties id="javaMailProperties">

請添加更多標籤，你的問題。這看起來不像Spring集成問題。您的IMAP服務器有一些限制。 –

謝謝，添加標籤imap和javamail –

好。但我仍然認爲你應該爲你的電子郵件服務器添加標籤。這可能根本不是Java客戶端問題。 –

NOT（*****）命令不是由我的郵件服務器的支持，因此下面的命令不起作用

A5 SEARCH NOT (ANSWERED) NOT (DELETED) NOT (SEEN) NOT (FLAGGED) ALL

因此，我將DefaultSearchTermStrategy更改爲我自己的一個，名爲UnseenSearchTermStrategy

@Component 
public class UnseenSearchTermStrategy implements SearchTermStrategy { 
    UnseenSearchTermStrategy(){ 
     super(); 
    } 
    @Override 
    public SearchTerm generateSearchTerm(Flags flags, Folder folder) { 
     return new FlagTerm(new Flags(Flags.Flag.SEEN), false); 
    } 
}

和下面的命令將郵件服務器上執行，效果很好

A5 SEARCH UNSEEN ALL
