Hello, I just found out that if someone selects to be notified of an e-mail message delivery, that the mail server will send out a response back to the user with that user's e-mail address and if any aliases were setup, it will also the target e-mail address like the following: Subject: Return receipt The original message was received at Fri, 20 Aug 2004 01:06:24 -0400 from [68.166.149.62] ----- The following addresses had successful delivery notifications ----- wppi@xxxxxxxx (successfully delivered to mailbox) (expanded from: <stevewest15@xxxxxxxx>) ----- Transcript of session follows ----- wppi@xxxxxxxxxxx Successfully delivered ------------------------------------------- Is there any way to block our mail server from sending out this information back?
