Hello, I recently configured Postfix 3.1.0 on a low-volume, Internet facing server. Mail operations are normal, but I had two questions regarding backscatter.
1. From what I understand, “backscatter” refers to e-mails such as non-delivery reports being sent back to the originator of a spam message. As the originator is often a forged address, the non-delivery reports is essentially junk data. Would this be a correct definition for the term ? 2. Is it possible to white-list the generation of non-delivery reports for some hosts and prevent generation for all others ? For instance, if a Gmail user attempts to e-mail me but specifies a non-existent address, I want the non-delivery report to go them (and any other senders from @gmail.com), but all other reports should be stopped from being sent. Thanks for your help, - J
