Has anyone integrated Challenge / Response, such as TMDA, into ISPConfig? We're a small-town utilities running wireless for our rural customers and the Spam thing is just getting out of hand. We'd like to implement some sort of Challenge / Response to help cut it down if we could. We currently run Ubuntu Breezy server with ISPConfig + ProcMail + SpamAssasin + AntiVirus but when we get plowed under during the day, the server just crawles under the load. It recovers but it has to be having to scan all that junk mail! It's a dual CPU Dell server with 2 gig of memory but still! We're kinda hoping that there would be a way to integrate a package like TMDA into this mix so we could enable it for some people and leave it off if the customer does not want it. We're drowning in SPAM! Help! John
Another thing to get down the load from spamscanning is to implement RBL in postfix or to use spamd with ISPConfig.
