Question

我必须使用JavaMail API向用户发送电子邮件。

用户可能拥有撇号的电子邮件地址，例如

 Michael.O’Hara@sampleDomain.com

当我尝试向这样的用户发送电子邮件时，我遇到了异常。

    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，那就太棒了。

Answer 1

假设允许带有`的电子邮件地址，我会尝试更改此

addressTO[i] = new InternetAddress(toAddressesArray[i]);

到这个

addressTO[i] = new InternetAddress(toAddressesArray[i].replace("`", "\\`"));

使用\。

跳过`字符

Answer 2

符合RFC2822“3.4.1。地址规范”＆amp; “3.2.5。带引号的字符串”如果它被转义，你可以使用这些字符（'）。

要转义单个字符，您可以使用“\”;转义多个字符使用双引号。以下地址将是有效的RFC2822地址： Michael.O \'Hara@sampleDomain.com “Michael.O'Hara” @ sampleDomain.com

PS很高兴看到完整的堆栈跟踪，可能是因为一些不同的问题你无法发送邮件。
