Your code has a slight problem that I see, the 'From:' header contain a newline between the name & the email, that may cause problems for your code.

This is not bug in PHP but in your code..please ask support elsewhere.

I have tried taking the new line breaks out of my previous code but am still getting the same result.  I have taken the code below from phpbuilder.com and put in my email address and the message "From then on" and the output was the same: >From then on 

<?php
	   mail("sarah@perceptiondesign.net", "the subject", "From then on",
       "From: webmaster@$SERVER_NAME\nReply-To: webmaster@$SERVER_NAME\nX-Mailer: PHP/" . phpversion());
       
	  ?>

It has to do with the unix mailbox format.

"From " at the beginning of a line is the seperator for emails in such a box, and to make sure normal lines with "From " at the beginning of a line are prefixed with a  ">".

Fixed the problem by replacing all instances of "From " with "<b></b>From " and this seems to work.  Thanks for your help Derrick.

<?php
		$xmessage = str_replace ("From ", "<b></b>From ", $message);
		
	  	echo "Emails have been sent to the following people: <br><br>";
		$header = "From: Blair Drummond Safari Park <info@blairdrummond.com>\n";
		$header .= "Content-Type: text/html\n";
	  	$db = mysql_connect("localhost", "safa16", "tybfg+nfcvf"); 
		mysql_select_db("safa16",$db);
		$result = mysql_db_query("safa16","select * from bd_consumers where email<>'' and email <> ' ' and mailing<>-1");
		while ($row = mysql_fetch_array($result)) {
			echo $row["email"]." (".$row["first_name"]." ".$row["surname"].") ";
			mail($row["email"],$subject,nl2br($xmessage),$header);
		}	 
	  ?>
