Changing br to \r\n without effecting email output

[wright67uk]

The code below returns the correct results, which are in this case are email addresses.

After each displayed value there is a br eg.  emai1@hotmail.com<br>email2@hotmail.com<br>email3@ etc.

So the quesion is, can i change the below codeing to prevent this.

I have tried changing

$message .= "<br>". $row['email']   to  
$message .= "\n". $row['email'] 

but this results in;

 

Warning: mail() [function.mail]: SMTP server response: 451 See http://pobox.com/~djb/docs/smtplf.html

 

so now i changed the line to

$message .= "\r\n". $row['email'] 

and my email displays perfectly.

 

The only problem now is that the email addresses and message are all on one line on screen, is there a way to get each of the returned email addresses to sit on a new line, without it bringing back those br br br's in my email output?

 

mysql_select_db("treesurgery") or die("Unable to select database"); 
$code = $_GET['postcode'];
$message = $_GET['message'];
$emailad = "email@hotmail.co.uk";
$shortcode = substr($code,0,2);
$result = mysql_query("SELECT email FROM treesurgeons WHERE postcode like '%" . $shortcode . "%' ORDER BY companyName LIMIT 3")
or die(mysql_error());  
echo "<h2>Business Names:</h2>";                     
while ($row = mysql_fetch_array( $result )) 
{
$message .= "\r\n". $row['email'] ;
}
echo $message; 
mail( "$emailad", "Header","$message" );
echo "<br>" . "Thank you for using our mail form.";

 

 

Thankyou

Surely you can just use the <p> tag?

The only thing with that is that instead of <br> following each row in my email, it would be <p> instead

changing;

echo $message;

to

echo nl2br $message;

seemed to clear this one up
