PHP mail()返回false但没有记录错误

dev*_*lis 3 php email

我为内容人员编写了一个快速而又脏的脚本,将新闻稿发送到通讯组列表.该脚本已经运行了好几个月,所以用PEAR邮件重写它一直是我的优先级列表中的低位.今天脚本无法发送电子邮件.mail()函数返回false,电子邮件没有出去,但error_get_last()为null.我该怎么做才能弄清楚脚本突然停止工作的原因?提前致谢!

<?php
ob_start();
readfile("/html-email/tt-facstaff");
$facstaff_content = utf8_decode(ob_get_contents());
ob_start();
readfile("/html-email/tt-students");
$students_content = utf8_decode(ob_get_contents());
ob_end_clean();
ob_end_clean();

if($students_content === false || $facstaff_content === false) die("<h4>Failed to decode content.</h4>");
$all_content = $facstaff_content."\n\n".$students_content;

if(isset($_GET["go"]) && $_GET["go"] == "true"){
    $ppl = "redacted";
    $students = "redacted";
    $facstaff = "redacted";

    $subject = "Tech Times for ".date("m/d");
    $headers = "From: \"Tennessee Tech University\" <redacted>\r\n".
        "Reply-to: redacted\r\n".
        "MIME-Version: 1.0\r\n".
        "Content-type: text/html; charset=iso-8859-1\r\n".
        "X-Mailer: PHP/".phpversion();

    $ok1 = mail($students,$subject,$students_content,$headers."\r\nBcc:".$ppl);
    $ok2 = mail($facstaff,$subject,$facstaff_content,$headers);

    if($ok1 && $ok2){
        echo("<html><body><div><h1 style=\"width:800px; margin:40px auto; text-align:center;\">Tech Times has been sent.</h1></div></body></html>");
    }else{
        $error = error_get_last();
        var_dump($error);
        echo("<html><body><div><h2 style=\"width:800px; margin:40px auto; text-align:center; color:#FF0000;\">Failed to send one or both editions of Tech Times!</h2></div></body></html>");
    }
}

echo $all_content;

  1. 检查sendmail是否在服务器上运行.
  2. 检查/ var/log/maillog
