Hi I have a simply working SMTP form, however I need this to send to a yahoo.com email address, what can I add to achieve this? SmtpConfig.php ============== <?php //Server Address $SmtpServer="91.186.30.25"; $SmtpPort="25"; //default $SmtpUser="things@wilsoncarandvanrental.co.uk"; $SmtpPass="things123"; ?> SmtpClass.php ============= <?php class SMTPClient { // A function for Setting up SMTP function SMTPClient ($SmtpServer, $SmtpPort, $SmtpUser, $SmtpPass, $from, $to, $subject, $body) { $this->SmtpServer = $SmtpServer; $this->SmtpUser = base64_encode ($SmtpUser); $this->SmtpPass = base64_encode ($SmtpPass); $this->from = $from; $this->to = $to; $this->subject = $subject; $this->body = $body; //Setting Default port Value if ($SmtpPort == "") { $this->PortSMTP = 25; } else { $this->PortSMTP = $SmtpPort; } } //Sending the Mail function SendMail () { if ($SMTPIN = fsockopen ($this->SmtpServer, $this->PortSMTP)) { fputs ($SMTPIN, "EHLO ".$HTTP_HOST."\r\n"); $talk["hello"] = fgets ( $SMTPIN, 1024 ); fputs($SMTPIN, "auth login\r\n"); $talk["res"]=fgets($SMTPIN,1024); fputs($SMTPIN, $this->SmtpUser."\r\n"); $talk["user"]=fgets($SMTPIN,1024); fputs($SMTPIN, $this->SmtpPass."\r\n"); $talk["pass"]=fgets($SMTPIN,256); fputs ($SMTPIN, "MAIL FROM: <".$this->from.">\r\n"); $talk["From"] = fgets ( $SMTPIN, 1024 ); fputs ($SMTPIN, "RCPT TO: <".$this->to.">\r\n"); $talk["To"] = fgets ($SMTPIN, 1024); fputs($SMTPIN, "DATA\r\n"); $talk["data"]=fgets( $SMTPIN,1024 ); fputs($SMTPIN, "To: <".$this->to.">\r\nFrom: <".$this->from.">\r\nSubject:".$this->subject."\r\n\r\n\r\n".$this->body."\r\n.\r\n"); $talk["send"]=fgets($SMTPIN,256); //CLOSE CONNECTION AND EXIT ... fputs ($SMTPIN, "QUIT\r\n"); fclose($SMTPIN); // } return $talk; } } ?> mail.php ======== <?php //Include Class And Config include('SmtpConfig.php'); include('SmtpClass.php'); //Check the Request Method if($_SERVER["REQUEST_METHOD"] == "POST") { $to = $_POST['to']; $from = $_POST['from']; $subject = $_POST['sub']; $body = $_POST['message']; // Send the mail Using the class $SMTPMail = new SMTPClient ($SmtpServer, $SmtpPort, $SmtpUser, $SmtpPass, $from, $to, $subject, $body); $SMTPChat = $SMTPMail->SendMail(); } // After Exit, show the form ?> <form method="post" action=""> To:<input type="text" name="to" /> From :<input type='text' name="from" /> Subject :<input type='text' name="sub" /> Message :<textarea name="message"></textarea> <input type="submit" value=" Send " /> </form> Probably quite straight form, but of course I don#t know how :0) Much appreciated.
