无法使用php mail（）函数发送电子邮件

Question

我试图在提交表单后向用户发送HTML电子邮件，但无法通过PHP mail()函数发送电子邮件。 最近2个小时我一直在做同样的事情，但找不到解决方案。

以下是我的代码，请提出您的建议。

<?php
$replyemail="sales@companyname.com";

if (!isset($_POST['email']))
{
 echo "<script language=\"JavaScript\"><!--\n ";
 echo "top.location.href = \"$valid_ref1\"; \n// --></script>";
 exit;
}

function is_forbidden($str,$check_all_patterns = true)
{
 $patterns[0] = 'Content-Type:';
 $patterns[1] = 'mime-version';
 $patterns[2] = 'multipart/mixed';
 $patterns[3] = 'Content-Transfer-Encoding';
 $patterns[4] = 'to:';
 $patterns[5] = 'cc:';
 $patterns[6] = 'bcc:';
 $forbidden = 0;
 for ($i=0; $i<count($patterns); $i++)
  {
   $forbidden = eregi($patterns[$i], strtolower($str));
   if ($forbidden) break;
  }
 //check for line breaks if checking all patterns
 if ($check_all_patterns AND !$forbidden) $forbidden = preg_match("/(%0a|%0d|\\n+|\\r+)/i", $str);
 if ($forbidden)
 {
  echo "<font color=red><center><h3>STOP! Message not sent.</font></h3><br><b>
        The text you entered is forbidden, it includes one or more of the following:
        <br><textarea rows=9 cols=25>";
  foreach ($patterns as $key => $value) echo $value."\n";
  echo "Error";
  exit();
 }
 else return $str;
}

$email = is_forbidden($_POST["email"]);
$contact = is_forbidden($_POST["contact"]);
$comments = is_forbidden($_POST["comments"]);

$ccemail = "From: $email" . "\r\n" .
"CC: demo@companyname.com";

$mailHeader = "MIME-Version: 1.0\r\n";
$mailHeader .= "Content-type: text/html; charset=iso-8859-1\r\n";
$mailHeader .= "From: " . $email . "\r\n";
$mailHeader .= "Cc: demo@companyname.com\r\n";

$themessage = 'Hello';

mail("$replyemail","Thanks for Register","$themessage","$mailHeader");
?>

我也被卡住了一次。 我建议您尝试使用其他电子邮件地址（我发现邮件仅发送给gmail），如果该地址不起作用，请与您的托管服务联系（就使用PHP mail（）函数而言，免费托管是不可靠的） ）。
