Ask your ISP.

Mine said up to 250 or 250 an hour, 'but we can make an exception for
your IP address' or something. I have no more than 100 at the moment

here's my code - adjusted for anonymity
$employee _id contains the identity of the person using the mailer -
they are uses as the return and fro addresses.

$_POST['status'] selects a subset of the entire mailing list.

function sendmail()
{
global $employee_id;
if(isset($_POST['status']))
$status=$_POST['status'];
else return("-1");
if (strlen($_POST['body'])<1)
return ("-2");
else $body=stripslashes($_POST['body']);
$subject=$_POST['subject'];
$return_path="webmaster(at)mysite(dot)org";
$from=mysql_result(mysql_query(sprintf("select email
from people
where id='%d'",
$employee_id)),0,'email');
// get list of addressees
mysql_query("set group_concat_max_len = 8192");
//...to avoid truncation
// This bit gets a comma delimited array of email
// addresses disregarding those that have no '@' in them
$email=mysql_result(mysql_query(sprintf("select 1 as g,
group_concat(email separator ',') as them
from people
where status>='%d' and instr(email,'@')
group by g",$status)),
0,'them');
//
$headers = sprintf("From: %s\nBcc:%s\n", $from,$email);
mail('', $subject, $body, $headers, "-f ".$return_path );
return("");
}

That may serve as a starting point for you.
