我正在尝试使用我公司的邮件服务器发送电子邮件。但我得到以下例外
Caused by: com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.1 Client was not authenticated
at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:1388)
at com.sun.mail.smtp.SMTPTransport.mailFrom(SMTPTransport.java:959)
at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:583)
at javax.mail.Transport.send0(Transport.java:169)
at javax.mail.Transport.send(Transport.java:98)
这是我的示例代码，
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", "example.server.com");
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "true");
props.put("mail.smtp.port", "25");
// Get session
//Session session = Session.getDefaultInstance(props, null);
Session session = Session.getDefaultInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("username", "password");
}
});
// Define message
MimeMessage message = new MimeMessage(session);
// Set the from address
message.setFrom(new InternetAddress(from));
// Set the to address
message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
// Set the subject
message.setSubject("Hello JavaMail");
// Set the content
message.setText("Welcome to JavaMail");
// Send message
Transport.send(message);
什么代码错了？
与用户名和密码一样，我使用的是公司的电子邮件地址和密码。
5.7.1可能是由交换而不是您的代码引起的。您可能只需要在服务器上启用中继。对于匿名用户或来自某个IP地址。我不是交易所的专家，但我之前有这个工作。这是我测试的最后一个解决方案：
如果在用户通过身份验证时尝试通过SMTP在Exchange服务器上发送电子邮件时遇到5.7.1错误。
对于ref，您刚刚遇到的问题是由Exchange 2007服务器上的设置引起的 - 这在2003服务器上通常不会出现问题
修正如下...
您可以通过GUI设置此身份验证设置
- 在服务器配置/集线器传输/默认<ServerName>中
- 右键单击，属性，权限组
- 选中“匿名用户”，然后单击“确定”
显然，匿名用户不是太安全，但你可以看到这是否解决了这个问题。

Mail.jar（版本1.4.0）与MS Exchange Server和throws存在兼容性问题 530 5.7.1 Client was not authenticated，即使配置了用户名和密码。
将邮件API升级到1.4.4或1.4.7应该可以解决此问题。
Mail API的1.4.7可以从以下URL下载： http://www.oracle.com/technetwork/java/javamail/index.html
在某些公司中，Exchange服务器SMTP支持是禁用的，您无法要求它们启用它。在这些情况下，合理的解决方案是这样的：

简单的Java邮件 为我工作。你唯一需要检查的是正确的 主机名， 用户名， 港口 和 密码 TransportStrategy.SMTP_TLS：
new Mailer(host, port, username, password, TransportStrategy.SMTP_TLS).sendMail(email);
当我使用MS Exhange SMTP Server发送电子邮件时，我使用上面的maven依赖项。
<dependency>
<groupId>com.microsoft.ews-java-api</groupId>
<artifactId>ews-java-api</artifactId>
<version>2.0</version>
</dependency>
出于这个原因，我创建了一个代表MS Exchange Server的电子邮件客户端的类。我使用log4j进行日志记录。

<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>

一个工作的例子，
// import microsoft.exchange.webservices.data.core.enumeration.misc.ExchangeVersion;
ExchangeClient client = new ExchangeClient.ExchangeClientBuilder()
.hostname("webmail.domainOfWeb.com")
.exchangeVersion(ExchangeVersion.Exchange2010)
.domain("ActiveDirectoryDomain")
.username("ActiveDirectoryUsername")
.password("ActiveDirectoryPassword")
.recipientTo("recipient@whatever.com")
.recipientCc("recipient@whatever.com") // Ignore it in case you will not use Cc recipients.
.recipientBcc("recipient@whatever.com") // Ignore it in case you will not use Bcc recipients.
.attachments("/home/username/image.png") // Ignore it in case you will not use attachements.
.subject("Test Subject")
.message("Test Message")
.build();
client.sendExchange();
我不得不使用javamail + exchange。返回的消息很无奈。
感谢堆栈，我得到了一些提示。
将其添加到您的代码中
props.put("mail.smtp.starttls.enable","true");
考虑添加使用的机器的证书。
要找到它们，只需转到浏览器，导出它们并导入到 cacerts文件 正在使用。
请使用以下代码部分代替 Transport.send(message);
MimeMessage message = new MimeMessage(session);
message.saveChanges();
Transport transport = session.getTransport("smtp");
transport.connect(host, "user", "pwd");
transport.sendMessage(message, message.getAllRecipients());
transport.close();
我在当地进行了测试，它正在运行
