我正在使用以下示例代码：

我正在尝试使用我自己的服务器电子邮件发送电子邮件，而不打算使用Android

我变了：

    _host = "smtp.myserver.com"; // default smtp server 
    _port = "587"; // default smtp port 
    _sport = "587"; // default socketfactory port 

Mail m = new Mail("username@myserver.com", "password"); //to my sever email

我从未使用过此包装器，但代码假定SSL支持，而您的端口587服务器似乎不支持SSL。注释掉这两行

props.put("mail.smtp.socketFactory.port", _sport); 
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); 

并将这条线从false设置为true

props.put("mail.smtp.socketFactory.fallback", "false");

这可能会有所帮助。

如果我这样做，我会得到：01-31 21:31:22.989:E/MailApp（18069）：com.sun.mail.SMTPSendFailedException:5505.7.1访问被拒绝01-31 21:31:22.989:E/MailApp（18069）：在com.sun.mail.smtp.SMTPTransport.issueSendCommand（SMTPTransport.java:1515）您连接到的SMTP服务器是否配置为允许您通过它中继邮件？550 5.7.1访问被拒绝意味着您的代码成功连接到SMTP服务器，但服务器拒绝了您。我不知道，如果我可以将此电子邮件与Outlook一起使用，这意味着它允许通过它中继邮件，或者这意味着什么都没有？您应该能够使用正确的凭据进行中继，您正在向构造函数传递这些凭据。尝试在Mail类中打开_debugable，看看它是否在输出中提供了有用的东西。祝你好运谢谢，调试模式说我还需要更改m.setFrom（“username@myserver.com"); , 现在它可以工作了。如果我这样做，我得到了：01-31 21:31:22.989:E/MailApp（18069）：com.sun.mail.SMTPSendFailedException:550 5.7.1访问被拒绝01-31 21:31:22.989:E/MailApp（18069）：在com.sun.mail.SMTPTransport.issueSendCommand（SMTPTransport.java:1515）您连接的smtp服务器是否配置为允许您通过它中继邮件？550 5.7.1访问被拒绝意味着您的代码成功连接到SMTP服务器，但服务器拒绝了您。我不知道，如果我可以将此电子邮件与Outlook一起使用，这意味着它允许通过它中继邮件，或者这意味着什么都没有？您应该能够使用正确的凭据进行中继，您正在向构造函数传递这些凭据。尝试在Mail类中打开_debugable，看看它是否在输出中提供了有用的东西。祝你好运谢谢，调试模式说我还需要更改m.setFrom（“username@myserver.com"); , 现在它起作用了。
