(i.e. some software that send email, check for the bounced back email, and if there's not bounced back email, send an alert) I am looking for one right now, preferably open source but open to anything, to monitor our email flow. Any recommendation? Thanks, Albert ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
