Question

我在专用服务器上安装了PHPList（3.2.4）。我目前没有设置特定的配置或限制。我使用本地后缀作为SMTP。

我发送了一个广告系列和一个电子邮件地址，收到以下错误（在maillog中）：

import java.io.*;
import weka.classifiers.Classifier;
import weka.classifiers.Evaluation;
import weka.classifiers.evaluation.NominalPrediction;
import weka.classifiers.meta.AdaBoostM1;
import weka.classifiers.trees.RandomForest;
import weka.core.FastVector;
import weka.core.Instances;

public class ULCWekaTest
{

   public static Evaluation classify(Classifier model,
                                     Instances trainingSet, Instances testingSet)
      throws Exception
   {
      Evaluation evaluation = new Evaluation(trainingSet);

      model.buildClassifier(trainingSet);
      evaluation.evaluateModel(model, testingSet);

      return evaluation;
   }

   public static double calculateAccuracy(FastVector predictions)
   {
      double correct = 0;

      for(int i = 0; i < predictions.size(); i++)
      {
         NominalPrediction np = (NominalPrediction) predictions.elementAt(i);
         if(np.predicted() == np.actual())
            correct++;
      }

      return 100 * correct / predictions.size();
   }

   public static void main(String[] args) throws Exception
   {
      String basepath =
         "/Users/Ebe/Pantheon/Ares/PhD/Course Work/MLT/MLT-Lab/Mini Project/Implementation/";

      Instances trainData;
      try(BufferedReader reader =
         new BufferedReader(
            new FileReader(basepath + "train80.arff")))
      {
         trainData = new Instances(reader);
         reader.close();
      }
      trainData.setClassIndex(0);

      Instances testData;
      try(BufferedReader reader =
         new BufferedReader(
            new FileReader(basepath + "test80.arff")))
      {
         testData = new Instances(reader);
         reader.close();
      }
      testData.setClassIndex(0);

      Classifier forest, adaboost;
      String[] options = new String[2];

      for(int i = 100; i < 500; i+=2)
      {
         for(int s = 6; s <= 6; s++)
         {
            adaboost = new AdaBoostM1();
            forest = new RandomForest();
            //for(String str : forest.getOptions())
               // System.out.println(str);   
            options[0] = "-I";
            options[1] = ""+i;
            forest.setOptions(options);

            options[0] = "-S";
            options[1] = "" + s;
            forest.setOptions(options);

            adaboost.setClassifier(forest); // <-- COMPILER ERROR AT THIS POINT
            // Collect every group of predictions for current model in a FastVector
            FastVector predictions = new FastVector();
            // For each training-testing split pair, train and test the classifier
            Evaluation validation =
               classify(adaboost, trainData, testData);
            predictions.appendElements(validation.predictions());

            // Calculate overall accuracy of current classifier on all splits
            double accuracy = calculateAccuracy(predictions);
         // Print current classifier's name and accuracy in a complicated,
            // but nice-looking way.
            System.out.println("-I " + i + " -S " + s + ": " + String.format(
               "%.2f%%", accuracy));
         }
      }
   }
}

问题是phplist一直试图将消息发送到该地址，并且它不会停止活动。这不是反弹，而是电子邮件失败，因此广告系列永远不会关闭，而且在管理界面中，我不断收到消息：

Recipient address rejected: Domain not found

因此我必须手动停止广告系列。

我想知道我是否可以：

在重试之间设置超时
在N次重试后将此地址标记为无效

我阅读了文档，但没有找到我正在寻找的内容。如何实现此结果并避免phplist无限期地重试发送到失败的地址？

这可能取决于我的Postfix配置吗？（例如拒绝而不是反弹）？
