I am running a mail server and I pay per GB transfered. If I have my ISP do the limiting, they charge extra $$ for it. I know I can limit incoming mail size via the mail server. But still doesn't prevent someone from sending a lot of mail or fill up a 100mbps line for 24 hrs/day. I am not looking for a perfect solution, and I do realize ddos attacks and such are still possible. I am only looking for a reasonable solution.
