RE: [PHP-DB] newsletter optimization help needed

I've been doing that with a much smaller list, and we periodically run into problems with subscribers SPAM filter, double-propagation of some addresses, etc. I think the days of bcc: are numbered. The approach we're working on now is to send an URL to subscribers. They click on that and view the newsletter through Flash player. As for Chris's problem, I don't know. I'd be tempted to have the PHP script pass a set of parameters to a Python script and then end. When the Python script completes have that email the results to the user. A friend of mine used a similar process to handle requests for huge amounts of geological data. The parameters were passed to the database which generated the file and called a script to mail them. The original page was long since gone. Miles At 09:56 AM 3/12/2003 -0800, SELPH,JASON (HP-Richardson,ex1) wrote:

You could change the TO: to something generic like "Email List Subscriber" then add everyone to the BCC field and then generate 1 email with 9000 people in the BCC field. Let sendmail do the rest. It should take less time to send the emails and only a few seconds to generate your page.

The problem is I have over 9000+ email addresses in the DB and it takes around 30-45 minutes to send them with the below code. Can anyone see someway I can optimize it so it sends out the newsletter any faster? I've probably gone about this system the long way, but it works - I just need to find a way to make it faster :-( Thanks everyone All the best Chris --- <? $connection = mysql_connect("localhost","Username","Password") or die("Couldn't make a connection."); $db = mysql_select_db("WhateverDB", $connection)
