我在 Tomcat 6.0 上使用 Javamail 通过 linux 发送带有附件的电子邮件时遇到问题。

在我的机器（Windows 7 64）上使用 Tomcat 服务器发送邮件时，它工作正常。我已经使用本地 smtp 服务器和 gmail 帐户作为中继对其进行了测试。但是当我的远程 Tomcat 服务器运行 linux 发送邮件时，收到的邮件是一团糟，没有主题，附件显示为文本（原始是 pdf 文件），并且一些邮件标题与邮件混合在一起。我尝试使用在 Windows 上进行测试时使用的相同方法：尝试本地 smtp 服务器，然后使用 gmail 作为中继。它在这两种情况下都不起作用。

我还尝试更改我的本地 JavaMail 库，并使用我们在远程服务器上的相同库（从服务器复制到我的机器），但在本地运行的结果总是相同的。电子邮件以预期的方式收到。

当我发送电子邮件时，它会发送另一个副本给我，这样我就可以跟踪正在发生的事情。下面的日志显示了使用我的 j2ee.jar 中嵌入的 Javamail 运行本地测试时两个邮件（原始邮件和副本）的 Javamail 输出（有关详细信息，请参见下文）：

在我的远程服务器中，我们在 context/WEB-INF/lib 上有 JavaMail 库。我们有一个 mail.jar 和一个 j2ee.jar，其中还包含 JavaMail。此外，在 tomcat 文件夹中还有另一个 mail.jar（可以在日志中看到）和另一个包含 Javamail 的 j2ee.jar。

我尝试用最近的替换服务器的 /WEB-INF/lib/mail.jar，但日志甚至没有改变。在我的本地测试中使用来自服务器的 .jars 会产生正确的结果。

请注意，我的服务器没有显示一些应该存在的调试行。

以下是用于发送电子邮件的代码：

Properties props = new Properties();
props.put("mail.smtp.debug", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.mime.charset", "ISO-8859-1"); 
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.starttls.required", "true");
props.put("mail.smtp.host", smtpHost);
props.put("mail.smtp.port", Integer.toString(port));
this.session = Session.getInstance(props,
    new javax.mail.Authenticator() {
      protected PasswordAuthentication getPasswordAuthentication() {
         return new PasswordAuthentication(usr, pass);
      }
});

MimeMultipart mp = new MimeMultipart("mixed");
MimeBodyPart txtPart = new MimeBodyPart();

if(this.message == null){
    if(this.session != null){
       this.message = new MimeMessage(this.session);
    } else {
       throw new Exception("");
    }
}

this.session.setDebug(true);
this.message.setFrom(new InternetAddress(this.from));
this.message.setRecipient(Message.RecipientType.TO, new InternetAddress(this.to));
this.message.setSubject(this.subject);

txtPart.setDisposition(Part.INLINE);
txtPart.setText(text);
mp.addBodyPart(txtPart);

for (int i = 0; i < this.attach.size(); i++) {
    MimeBodyPart filePart = new MimeBodyPart();
    File file = (File) this.attach.elementAt(i);
    FileDataSource fds = new FileDataSource(file);
    DataHandler dh = new DataHandler(fds);
    filePart.setFileName(file.getName());
    filePart.setDisposition(Part.ATTACHMENT);
    filePart.setDescription("Attached file: " + file.getName());
    filePart.setDataHandler(dh);
    mp.addBodyPart(filePart);
}

this.message.setContent(mp);

Transport.send(this.message);

需要任何进一步的细节，请询问。

感谢您的考虑！

尝试从您的应用程序中删除 j2ee.jar；其中包含一些 JavaMail 类的非常旧版本，可能与 mail.jar 中的较新版本冲突。

（j2ee.jar 只打算在编译时使用；它不应该在运行时使用。）
