I don't know how to do it with Courier as I use Postfix - and if you ask your question on the Postfix-ML, which is IMHO *the* ML with the most knowledgeable mail admins ever seen, you will receive exactly the same answer: Don't do it! Use things like sender verification, RBLs and alike but don't reject mails from <>! See, let's assume you reject mails from <>. You write a mail to [EMAIL PROTECTED] You ment juri but you wrote jiri. Your mail cannot be delivered at my site, so my mail server writes a mail from <> to you, explaining that jiri isn't a valid user and your mail could *not* be delivered. You will never receive this bounce, 'cause you rejected all mails from <>. So you will assume that I received your mail. Now think about a very important businuess mail you wanted to send and you wonder, why I don't like you proposal...
