Hi there, I am currently working out an Email System for outbound Emailing, the client I work wants to send out large Mailings to his customers, and past customers. I expect alot of Bounces and have found that AOL for example uses Feedback Loops ( http://postmaster.aol.com/fbl/ ) to inform the sender about Mail Recpients that do not wish to be Emailed from the Mailing List. This would benefit us since we can remove the user from the Database and not harass that email Server again.
Does anyone know other ISP'S that are using FBL ? So far I could only find AOL and USA.net Thanks in Advance Kind Regards Christian Keil
