Question

我的应用程序遍历了电子邮件收件人，其中一些收件人的地址可能不正确。当遇到不良情况时，我希望将其报告给用户，并使循环继续进行。问题是即使我捕获了所有可能的异常，SMTPAddressFailedException也被javax捕获了：

javax.mail.SendFailedException：地址无效；嵌套的异常是： com.sun.mail.smtp.SMTPAddressFailedException：550 5.1.1：收件人地址被拒绝：虚拟邮箱表中的用户未知

，其余收件人将被跳过。处理此问题的正确方法是什么？

这是代码；

            List<Entry> theEntries = theConcours.GetEntriesList();
        for(Entry entry : theEntries){
            MasterPersonExt mp = aConcours.GetMasterPersonnelObject().GetMasterPerson(entry.GetOwnerUnique()) ;
            String owneremail = mp.getEmail();
            String ownername = mp.getFirstName() + " " + mp.getLastName();
            curOwnerUniqueName = mp.getUniqueName();
            System.out.println("Processing " + mp.getUniqueName() + " email: " + owneremail);
            MimeMessage message = new MimeMessage(session);  
            try {  
                message.setFrom(new InternetAddress(mailuser));
                System.out.println("From set while processing " + curOwnerUniqueName);
            } catch (AddressException ex) {
                String msg = "AddressException for: " + mailuser + " while processing " + curOwnerUniqueName;
                //Logger.getLogger(SendMailSSL.class.getName()).log(Level.SEVERE, null, ex);
                okDialog(msg);
                aConcours.GetLogger().log(Level.INFO, msg, ex);
                continue;

我通过实现一个名为sendMailToAnEntrant（）的帮助器函数解决了该问题，然后for循环在try-catch中仅调用了sendMailToAnEntrant（）。这将导致捕获javax代码引发的异常。似乎可以工作。

            for(Entry entry : theEntries){
        try {
            //sendMailToAnEntrant(Concours aConcours, String aFromEmailAddress, String aSubject, String aContentTemplate, String [] aTags, Entry aEntry, Session aSession)
            sendMailToAnEntrant(aConcours, mailuser, "Your JCNA Concours Entry", content_template, theTags, entry, session);
        } catch (MessagingException ex) {
            MasterPersonExt mp = aConcours.GetMasterPersonnelObject().GetMasterPerson(entry.GetOwnerUnique()) ;
            String owneremail = mp.getEmail();
            String ownername = mp.getFirstName() + " " + mp.getLastName();

            String msg = "Messaging Exception in sendMailToAnEntrant() for: " + ownername + " Email: " + owneremail;
            System.out.println(msg);
            okDialog(msg);
            aConcours.GetLogger().log(Level.INFO, msg, ex);
            //Logger.getLogger(SendMailSSL.class.getName()).log(Level.SEVERE, null, ex);
            continue;
        }
