客户端无权作为此发件人发送 |适用于 JavaMail API 1.4 但不适用于 1.4.7

Question

我发现了一个类似的问题，并且在使用与 name 不同的用户名发送电子邮件时遇到了同样的问题。我的私人交换服务器中的配置已到位，以将用户名标记为来自名称的别名。

com.sun.mail.smtp.SMTPSenderFailedException: 550 5.7.1 Client does not have permissions to send as this sender

当我使用 Java 邮件 1.4 版本的 API 时，我可以使用别名发送电子邮件。但是，如果我使用 1.4.7 版本，同样会失败。我假设任何高于 1.4 的版本都不起作用。有没有人遇到过同样的情况？以后的版本是否增加了安全配置或者需要传递的额外参数？

使用 JavaMail v1.4.7 发生错误时的会话调试日志如下：

Answer 1

使用 JavaMail 1.4.7 时，您正在对 SMTP 服务器进行身份验证。使用 JavaMail 1.4 时，您没有进行身份验证。您配置身份验证的方式会导致不同的行为。也许你在做

props.setProperty("mail.smtp.auth", true);

而不是

props.setProperty("mail.smtp.auth", "true");

在 JavaMail 1.4 中，第一个导致该属性设置为 false。在 JavaMail 1.4.7 中，它现在将字符串和原始对象作为值处理并将属性设置为 true。

但我不知道为什么您的服务器在您进行身份验证时拒绝该消息，但在您匿名时接受它。

（另外，您需要更改密码 - base64 编码的 PLAIN 身份验证输出包括您的密码。）
