我有一个脚本应该让服务器发送电子邮件。我的问题是，我可以通过电子邮件发送我的服务器并接收该电子邮件，但服务器不会发送电子邮件。只会通过 squirrelmail 界面发送电子邮件。我的 MX 记录为：mail.mydomain.com 和 mydomain.com 以及 mail.mydomain.com 的 A 记录
下面是应该让服务器发送电子邮件的脚本。
<?php
$fileatt = "Reports/$previousreport/$previousreport.pdf"; // Path to the file
$fileatt_type = "application/pdf"; // File Type
$fileatt_name = "$previousreport"; // Filename that will be used for the file as the attachment
$email_from = "example.com"; // Who the email is from
$email_cc = "example@example.com";
$email_subject = "$theData3"; // The Subject of the email
$email_message = "<br>";
$email_message .= "<br>"; // Message that the email has in it
$email_to = "$theData2"; // Who the email is to
$headers = "From: ".$email_from.
$headers = "\r\nCc: ".$email_cc;
$file = fopen($fileatt,'rb');
$data = fread($file,filesize($fileatt));
fclose($file);
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";
$email_message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$email_message .= "\n\n";
$data = chunk_split(base64_encode($data));
$email_message .= "--{$mime_boundary}\n" .
"Content-Type: {$fileatt_type};\n" .
" name=\"{$fileatt_name}\"\n" .
//"Content-Disposition: attachment;\n" .
//" filename=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data .= "\n\n" .
"--{$mime_boundary}--\n";
$ok = @mail($email_to, $email_subject, $email_message, $headers);
if($ok) {
echo "<font face=verdana size=2><center>You file has been sent<br> to the email address you specified.<br>
Make sure to check your junk mail!";
} else {
die("Sorry but the email could not be sent. Please go back and try again!");
}
?>
我一直在检查 MX 记录，但我不知道出了什么问题。
