我正在使用cpanel服务器，我在我的脚本中得到了这个类，实际上我不知道他们是如何发送电子邮件的。我在这里得到错误。我的Smtp课程是

和我发送的数学代码是
$smtp = new Smtp();
$smtp->host = "mail.server.com";
$smtp->port = "25"; / testted also 465/587 all port
$smtp->authenticate = "true";
$smtp->username = "[email protected]";
$smtp->password = "password";
$emailer = @sendMail($to, $subj, $msg, $from, $langx['charset']);
echo $debug;

220-server ESMTP Exim 4.91＃1 Tue，12 Mar 2019 15:04:48 -0400 220-我们不授权使用此系统来传输未经请求的220和/或批量电子邮件。 HELO mail.server.com 250服务器Hello mail.server.com [xxx.xxx.xxx.xxx] AUTH LOGIN 503未通告时使用的AUTH命令MAIL FROM：250 OK RCPT TO：550认证失败DATA QUIT
您的邮件服务器不支持身份验证，这意味着它可能会让您从源IP发送权限而不是ID和密码。您还使用了一个应该是布尔值的字符串;将$smtp->authenticate设置为true，而不是"true"，但由于您的邮件服务器无论如何都不支持它，您应该将其设置为false。
另外，当你不使用PHPMailer时，请不要用PHPMailer标记问题 - 尽管你应该这样做，而不是重新发明轮子？
