Problem using fputs to send commands to SMTP server

[f50bodykit]

Hello, Im having trouble using fsockopen and fputs to send email through an smtp server. I tried manually issueing the commands and it works great through telenet, but when i try to do the same with a php script I get this.

220 csun.edu Microsoft ESMTP MAIL Service, Version: 6.0.3790.0 ready at Tue, 25 Nov 2003 14:25:44 -0800
15
250-csun.edu Hello [130.166.1.1]

30
250-TURN
31
250-SIZE 2097152
6
250-ETRN
21
250-PIPELINING
3
6
250-DSN

I dont know what the TURn,ETRN, DSN and PIPELINING messages are.

This is the code that yielded the above result

<?php

   $fp = fsockopen ("130.166.1.1", 25);
   echo fgets ($fp,128);
          echo "<br>"; 
echo fputs($fp, "EHLO csun.edu\r\n");

            echo "<br>"; 
echo fgets ($fp,128);
echo "<br>"; 
echo fputs($fp, "MAIL FROM:<[e-mail]>\r\n");

            echo "<br>"; 
echo fgets ($fp,128);
echo "<br>"; 
echo fputs($fp, "RCPT TO:<[e-mail]>\r\n");

            echo "<br>"; 
echo fgets ($fp,128);
echo "<br>"; 
echo fputs($fp, "DATA\r\n");

            echo "<br>"; 
echo fgets ($fp,128);
echo "<br>"; 
echo fputs($fp, "This is the letter\r\n");

            echo "<br>"; 
echo fgets ($fp,128);
echo "<br>"; 
echo fputs($fp, ".\r\n");
echo "<br>"; 
echo fputs($fp, "QUIT\r\n"); 

            echo "<br>"; 
echo fgets ($fp,128);
echo "<br>"; 
fclose ($fp);

?>

I issued the same commands by telenetting into the server and it worked fine. Any suggestions or input would be greatly appreciated. I have tried searching google for what TURN, and PIPELINING mean but havent found anything that helps. Thanks.

Edit-
Thought it might be helpful if i added what i type when i telnet into the server.

Telnet 130.166.1.1 25

HELO blah
MAIL FROM: [e-mail]
RCPT TO: [e-mail]

DATA

This is a message

.

QUIT

and it all works fine and i get the email at [e-mail]

After a few hours of fiddling i found out that if I do this it works. I've done simillar stuff on other servers with out the need for the fgets, I dont know why i need it now.

<?php

$fp = fsockopen ("130.166.1.1", 25);

                            echo fgets ($fp,128);    
	echo "<br>"; 
	echo fputs($fp, "EHLO csun.edu\r\n");
	echo "<br>"; 
	echo fgets ($fp,128);
	echo fgets ($fp,128);
	echo fgets ($fp,128);
	echo fgets ($fp,128);
	echo fgets ($fp,128);
	echo fgets ($fp,128);
	echo fgets ($fp,128);
	echo fgets ($fp,128);
	echo fgets ($fp,128);
	echo fgets ($fp,128);
	echo fgets ($fp,128);
	echo fgets ($fp,128);
	echo "<br>"; 
	echo fputs($fp, "mail from: [email][e-mail][/email]\r\n");
	echo "<br>"; 

	echo fgets ($fp,128);
	echo "<br>"; 
	echo fputs($fp, "rcpt to: [email][e-mail][/email]\r\n");
echo "<br>"; 

	echo fgets ($fp,128);
	echo "<br>"; 
	echo fputs($fp, "data\r\n");
	echo "<br>"; 

	echo fgets ($fp,128);
	echo "<br>"; 
	echo fputs($fp, "letter is this \r\n");
	echo "<br>"; 

	echo fgets ($fp,128);
	echo "<br>"; 
	echo fputs($fp, ".\r\n");
	echo "<br>"; 

	echo fputs($fp, "QUIT\r\n"); 
	echo "<br>"; 
	echo fgets ($fp,128);
	echo "<br>"; 
	fclose ($fp);
