php邮件与outlook无法完美配合

Question

I have a problem using PHP to send mail. The mail is received by Outlook correctly, but it does not show the "From" address in the e-mail.

$subject = $_POST['message_subject'];
$message = $_POST['speaker_description'];
$email   = $_POST['email'];
$option  = $_POST['sel_reg_options'];
$email   = substr_replace($email ,"",-1);

$headers .= "Content-type: text/html; charset=iso-8859-1
";
$headers .= "From:My Name<[e-mail]>
";
$headers .= "Reply-To: Registration of Interest<[e-mail]>
";          
$headers .= "MIME-Version: 1.0"."
";
$mail_sent = @mail($email,$subject,$message,$headers);

Answer 1

You should enclose the name in double quotes (this also applies to the Reply-To address name):

$headers .= "From: \"My Name\" <[e-mail]>
";

Also, if running PHP on Unix, add the FROM envelope to the $additional_parameters parameter:

$mail_sent = @mail($email,$subject,$message,$headers,'-f [e-mail]');

On the contrary, if running on Windows, set the sendmail_from INI directive either in php.ini or by using:

ini_set('sendmail_from', '[e-mail]');
