Anyone know? Bouncing E-mail, simplified Process... 1. Sender contacts recpient via normal Internet transfer protocols. 2. Sender sends E-mail. If E-mail address is invalid, (i.e. user name spelled wrong) it 'bounces' back as an invalid address. Where the problem comes in, is that the way E-mail and the Internet is setup, E-mail messages are sent repeatedly any where from 4 hours to 5-6 days. This process itself is very intensive on the mail server. BTW, this is also the problem with replying to Spam messages with the remove line, it bounces back, causing all kinds of havoc, and further slow down at your ISP. :( It's a big weakness in the system, I've worked for an ISP that was attacked maliciosly with repeated ftp and mail requests from AOL, it actually caused our server to become so busy that clients couldn't get anywhere. On the other hand, y'all have to remeber the Internet was conceived originally as a means of communication between government and military computers in case of a Nuclear War, and as such was built from the ground up with redundancy in mind.
