Question

在我的项目中，我正在使用具有以下配置的imap空闲通道适配器：

@Bean
public IntegrationFlow imapAdapter(MailNotifierProperties properties, SubscribableChannel errorChannel,
                                       SubscribableChannel incomingMailChannel) {
    return from(Mail.imapIdleAdapter(properties.getImapUrl())
            .javaMailProperties(p -> p
                    .put("mail.imap.starttls.enable", "true")
                    .put("mail.imap.ssl.trust", "*"))
            .errorChannel(errorChannel)
            .shouldDeleteMessages(properties.getDeleteMessages()))
            .channel(incomingMailChannel)
            .get();
}

大多数情况下，配置工作正常。但是我每天一两次遇到以下异常，并且该应用程序无法处理大约30分钟的邮件：

现在我没有下列问题的答案 1）是什么导致错误消息：“ *没有邮箱已锁定，将在268秒后中止”？ 2）为什么在接下来的30分钟之内没有邮件处理？

更新：我已经检查了服务器上的日志文件，并且可以找到同时发生的以下消息：

Nov  18 07:05:33 MailServer postfix/local[19960]: 5D5AAC20FA: to=<sender@domain.com>, orig_to=<recipient@domain.com>, relay=local, delay=19, delays=0.01/0/0/19, dsn=4.2.0, status=deferred (cannot update mailbox /var/mail/mailUser for user mailUser. unable to lock for exclusive access: Resource temporarily unavailable)

但是，锁定邮箱的文件将在30秒后删除。

是否可以将imap通道适配器配置为在较短的时间内重新连接。我仍然有问题，该应用程序要等待30分钟才能重新连接到邮箱。

Answer 1

该邮件来自您的邮件服务器，因此您需要询问邮件服务器的所有者，或者如果它是您自己的邮件服务器，则需要查看日志文件，以查看其为何抱怨邮箱被锁定。也许有两个应用程序正在尝试访问同一邮箱，而邮件服务器一次不能处理一个以上的应用程序访问邮箱？

当imap空闲适配器在邮件收件箱上侦听时获取异常
