Hello all. We have a newsletter we send out to about 34,000 opt-in subscribers every other Thursday. The emails are all sent from an ASP page using CDOSYS on Windows 2000 Server. The smart-host for that SMTP engine is our Exchange 2003 box. Whenever that day comes around and we send out the newsletter, our email comes to a halt for all intents and purposes. It could take 2 days to send or receive a message if it's sent a few hours after the newsletter is mailed out. Interestingly enough, if I reboot the exchange server things operate at normal speed for about 10 minutes, and then everything grinds to a halt again. It slows down both inbound and outbound emails. I'm wondering if there isn't a better way to do this. I can't find much help on the web because everyone assumes you're a spammer if you're trying to send many emails. I can't find any best-practice documents on this subject. Surely there is a supported way for legitimate businesses to send newsletters to their customers through Exchange 2003. If not, does everyone use another product? Is sending with CDOSYS in ASP slowing me down?

That doesn't make it efficient. > If not, does everyone use another product? Is sending > with CDOSYS in ASP slowing me down? Exchange is not the tool you want for this job. Look into a real listserver like Lyris or similar - something that can serially send messages out and handle unsubscribe/bounces properly.
