Send Signed e-mail through smtp

[eu_rato]

Hi all,

 

I'm new to php, that's the reason i ended up here 

 

I'm using the code below to send signed messages, the message cames good in some "system's", but in other's doesn't.

 

Is it possible to send the certificate along with the mail message?!?!

This code is right?!?!?! Or exists better code to do the same?!?!

 

 

$fp = fopen("C:\msgnewsletter.txt","w");

fwrite($fp,"Content-Type: text/html;charset=\"iso-8859-1\"Content-Transfer-Encoding: quoted-printable" . $body);

fclose($fp);

openssl_pkcs7_sign("C:\msgnewsletter.txt", "C:\signedmsg.eml", "file://C:\lettercert.pem",array("file://C:\letterprivkey.pem","PASSWORD"),array("To" => "$to","From" => "$this->FromAddress", "Subject" => "$subject"),PKCS7_DETACHED);

$file_arry = file("C:\signedmsg.eml");

$file = join ("", $file_arry);

$message = preg_replace("/\r\n|\r|\n/", "\r\n", $file);

 

$fp = fopen("c:\signedmsg.eml", "wb");

flock($fp, 2);

fputs($fp, $message);

flock($fp, 3);

fclose($fp);

 

rename("c:\signedmsg.eml", "C:\Inetpub\mailroot\Pickup\signedmsg.eml");

 

 

Thanks in advance.
