Amy, do a google search for "email marketing" and you'll get a slew of possibilities (such as http://www.liszt.com/). My org uses Mailman running on a FreeBSD box with Postfix, but our lists are nowhere near as large as yours. Given your list requirements, you might want to consider outsourcing this functionality to a provider who's already set up to handle such things.

We are a online stock trading company. We get over 500,000 new clients a month. We are getting killed with badmail. We need to buy or develop software that goes out and verifies that an email address is valid. This way we can keep our distribution list under control. Does that help? -----Original Message----- From: Mulnick, Al [mailto:Al.Mulnick@xxxxxxxxxx] Sent: Wednesday, October 27, 2004 11:53 AM To: [ExchangeList] Subject: [exchangelist] RE: Spider Programs http://www.MSExchange.org/ Can you define that type of program for us? I suspect we're talking about different things here. To me, a spider program is one that crawls a website (or several) and looks for broken links. What you're looking for is a mass-mailing program *I think*. One that can help you track NDR's and remove those from the list later. Preferrably one that does self-service opt-in functionality because you're not a spammer, right? More information would be helpful. -----Original Message----- From: Amy Kohler [mailto:akohler@xxxxxxxxxxxxx] Sent: Wednesday, October 27, 2004 12:23 PM To: [ExchangeList] Subject: [exchangelist] Spider Programs http://www.MSExchange.org/ Hello all, I am working for company that has about 1,000,000 external clients that we sand mass emails. We are considering implementing a Spider program to help cut down NDR's. Does anyone know of any good 3rd party solutions? Thanks amy
