There is some similar functionality in postfix to stop spam. It has the option to enforce rules such as the reverse mappings must make sense or that what the MTA says for the helo or ehlo makes sense. Pinging isn't necessarily good. You can't ping my mail server. Or rather you can try, but you won't get a response. Learning more abuot these features of postfix is one of my immediate goals. I've been using exim but want to switch over to postfix for my main mail filter and server. Here is a page that talks about UCE control: http://www.postfix.org/uce.html Stopping spam at the mta level is more efficient in my book. Why spend precious time, cpu cycles and bandwidth to accept a bunch of spam just to quarantine it and then waste MY TIME to look at it? Instead have the MTA require certain things, like that the server that is connecting to it is configured properly. Much better to have the MTA determine as quickly as possible that it isn't going to receive any mail from a connecting MTA and terminate the conversation right there.
