You should have already had a process in place for "list vetting" before you decided to send bulk email on behalf of a "client". You are functioning as an Email Service Provider or "ESP" in your current described capacity, or you are simply a spammer. If you are bulk emailing on behalf of a client _without_ already having a list vetting process in place then you _ARE_ a spammer, by definition. If you are a trying to be a "legit" bulk mailer, you need to implement an automated COI process. COI - Confirmed Opt In. This means you have a closed loop system for web based subscriptions where people can sign up and remove themselves at will. Typically this is done with a mailing list manager program such as GNU Mailman or majordomo on *nix platforms. If you need to integrate this with a Microsoft database that's clue you will have to create yourself or acquire software that's already been written for this purpose. There surely already is as you can't be the first person to have such a need. DONT'T USE THIRD PARTY LISTS!! If your email subscribers actually want your mailings, setup a subscription URL that they can visit to sign up for your newsletters. The fact that you have done none of these things already shows that you are a spammer, whether you consider yourself one or not. There are masses of online resources that teach one to properly do legit bulk mailing. Google. If you _are_ a legit bulk mailer, I'd suggest you sign up with an ESP like Constant Contact and have them do your mailings for you. They have all of the vetting processes in place, and will teach you how to properly do legit bulk mailing, COI, etc. There obviously is a fee for their services, but it will be more than cost effective if you have legitimate subscribers who want your newsletters/product fliers/whatever. Your current "shoot from the hip" method of bulk mailing is never going to fly in today's world. This is why you're already listed on dns black lists and being wholesale rejected by Yahoo. Given your current methods, you need to immediately stop all of your bulk mailings until get a proper closed loop subscription service up and running, whether you do that in house or with an ESP like Constant Contact. If you are a legit bulk mailer, please have a Merry Christmas. If you are a spammer, choke on your eggnog. -- Stan
