我正在尝试在 java 中发送邮件,但我不断收到此错误“com.sun.mail.smtp.SMTPSendFailedException: 550 failed to meet SPF requirements”,我在互联网上搜索是否有其他人在 java 中遇到此问题并发现没有什么。任何人都知道这个错误意味着什么?我发送电子邮件的代码如下。
//Create session and message
Properties props = System.getProperties();
props.put("mail.smtp.user", user);
props.put("mail.smtp.password", password);
props.put("mail.smtp.auth", "false");
props.put("mail.smtp.host", mailhost);
javax.mail.Authenticator auth = null;
auth = new javax.mail.Authenticator() {
@Override
public javax.mail.PasswordAuthentication getPasswordAuthentication() {
return new javax.mail.PasswordAuthentication(user, password);
}
};
session = Session.getInstance(props, auth);
Message msg = new MimeMessage(session);
//Set from,recipients,content and other stuff here
//...................
//Send the message
Transport.send(msg);
