Ok, I've fixed my problem.
Rather than have my php scripts relay from one server to another, I have
them simply do it via an SMTP socket request. At the risk of not being
germane to Postfix, here's the code, FWIW:
(this uses 'Mail' and 'Mime' from Pear)
function send_out_mail($from, $subject, $html_body, $to)
{ $host = MAIL_SERVER_HOSTNAME;
$crlf = "\n";
// note that Bcc / cc must be in both the headers AND the send() call
$headers = array (
'From' => $from,
'To' => $to,
'Date' => date("r"),
'Subject' => $subject);
$mime = new Mail_mime($crlf);
$mime->setTXTBody(strip_tags($html_body));
$mime->setHTMLBody($html_body);
$total_body = $mime->get();
$headers = $mime->headers($headers);
$params = array (
'host' => $host,
'auth' => false);
$params['localhost'] = hostname();
$smtp = Mail::factory('smtp', $params);
$send = $smtp->send($to, $headers, $total_body);
if (PEAR::isError($send))
{ echo send->getMessage();
return 0;
}
else
{ return 1;
} }
