java - 电子邮件地址中的撇号引发异常

Question

我必须使用 JavaMail API 向用户发送电子邮件。

用户的电子邮件地址可能带有撇号，例如

 Michael.O’Hara@sampleDomain.com 

当我尝试向此类用户发送电子邮件时，出现以下异常。

    javax.mail.MessagingException: Can't send command to SMTP host;
  nested exception is:
    java.net.SocketException: Software caused connection abort: socket write error
    at com.sun.mail.smtp.SMTPTransport.sendCommand(SMTPTransport.java:1564)
    at com.sun.mail.smtp.SMTPTransport.sendCommand(SMTPTransport.java:1551)
    at com.sun.mail.smtp.SMTPTransport.close(SMTPTransport.java:696)
    at javax.mail.Transport.send0(Transport.java:191)
    at javax.mail.Transport.send(Transport.java:118)
    at com.openpages.ext.duke.util.DukeEmailUtil.sendNotification(DukeEmailUtil.java:194)

以下是我用来发送电子邮件的方法

public static void sendNotification(String mailServer, String fromName,
            String fromAddress, String toAddress, String ccAddresses,
            String subject, String emailContent) throws Exception {
        try {

            // TODO: The email session should be cached in a future release.
            Properties props = new Properties();
            props.put("mail.smtp.host", mailServer);

            Session session = Session.getInstance(props, null);
            MimeMessage msg = new MimeMessage(session);
            InternetAddress addressFrom = null;
            if (StringUtil.isGood(fromName))
                addressFrom = new InternetAddress(fromAddress, fromName);
            else
                addressFrom = new InternetAddress(fromAddress);
            msg.setFrom(addressFrom);

            if (toAddress != null && !toAddress.equalsIgnoreCase("")) {
                String[] toAddressesArray = toAddress.split(";");
                InternetAddress[] addressTO = new InternetAddress[toAddressesArray.length];
                for (int i = 0; i < toAddressesArray.length; i++) {
                    LoggerFactory.getLogger().error("Before InternetAdress Contructor");
                    addressTO[i] = new InternetAddress(toAddressesArray[i]);
                    LoggerFactory.getLogger().error("After InternetAdress Contructor");

                }
                msg.setRecipients(Message.RecipientType.TO, addressTO);
            }

            // TODO : method signature has to be changed
            // to take String[] for toAddress & ccAddresses
            if (ccAddresses != null && !ccAddresses.equalsIgnoreCase("")) {
                String[] ccAddressesArray = ccAddresses.split(";");
                InternetAddress[] addressCC = new InternetAddress[ccAddressesArray.length];
                for (int i = 0; i < ccAddressesArray.length; i++) {
                    addressCC[i] = new InternetAddress(ccAddressesArray[i]);
                }
                msg.setRecipients(Message.RecipientType.CC, addressCC);
            }

            msg.setSubject(subject, "utf-8");
            msg.setContent(emailContent, "text/html;charset=utf-8");
            Transport.send(msg);

            msg = null;
            session = null;
        }

        catch (Exception e) {
            e.printStackTrace();
            throw e;
        }
    }

如果有人能告诉我如何解决这个问题，那就太好了。

有两种可能的方法来处理这个问题(不知道你的代码到底是什么样子，如果你可以发布一些代码来显示消息是如何发送的，那就太酷了)。

• 使用 strict=false 例如new InternetAddress("Michael.O’Hara@sampleDomain.com", false)
• 除了上述方法之外，还可以将电子邮件地址本身放在双引号中，尽管这只是一种解决方法
• 放宽对Session对象的严格验证session.setProperty("mail.mime.address.strict", "false");
