Java IMAP电子邮件通道适配器引发异常“；A5错误无效的命令或参数&引用；

我在spring integration中使用imap空闲通道适配器接收电子邮件：

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

似乎imap服务器认为上述命令无效，有人能告诉我如何修复吗

假的

我的邮件服务器不支持NOT（****）命令，所以下面的命令不起作用

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

因此，我将DefaultSearchTermStrategy更改为我自己的一个，名为UnsenseArchTermStrategy

@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);
    }
}

下面的命令将在邮件服务器上执行，并且运行良好

A5 SEARCH UNSEEN ALL

请在问题中添加更多标签。这看起来不像是Spring集成问题。您的IMAP服务器有一些限制。谢谢，添加标记IMAP和javamailGood。但我仍然认为你应该为你的电子邮件服务器添加标签。这可能根本不是Java客户机的问题。
