Yes, it can, but not selectively. That is, if you want courier to be quiet about bad addresses, and bounce them, it will behave that way for your users and also for the internet at large. What will then happen is spammers will attempt dictionary attacks against your mail server to get valid addresses, and will generate all positives. They'll then send huge volumes of spam to your server, which courier would accept and then try to bounce. The spam would have a bad return address, and then sit undeliverable in your mail queue for a very long time before bouncing to the postmaster. The end result is that you can't read postmaster mail because there are too many messages, and you can't determine whether or not there's any valid problems with your mail server. The problem increases until your mail queue is full of thousands of messages which can't be delivered, and legitimate service degrades until it's not usable any more. Don't go down that road. It sucks. ------------------------------------------------------------------------- Take Surveys. Earn Cash.
