Wow! No not really but I was talking abouse people who were using aol.com accounts and psi.net accounts to send mail using us as a relay and then it uses the other machines as a relay too but all the mails will bounce to the postmaster address on our machine. =)I think perhaps you have to understand that if they were used as a =)relay for spam mail, they are going to get *FLOODED* with mail (I know =)from experience). Theres not a thing you can do (well, I stayed up all =)night once and fitted anti-relay rules to sendmail, but in the past =)they weren't available). Most people will just delete or refile the =)complaints, since they can't really do anything about the user =)originated them. Complaining to relays rarely does any good. Either =)they can't be bothered to fix it, or don't know how. Thats when cisco =)access list rules to block their mail hosts come in handy. I know what you mean here. We tried sendmail anti-relay rules. While it worked, there were more problems generated than it fixed. All I know is some companies use something other than sendmail they custom designed and had a way to kill the process but for icmp floods, the ISP would be responsible since it's a DoS attack.
