First, I want to thank the person who wrote this tutorial! One of the best I have encountered. I am somewhat new to Linux and I have successfully configured one of these spamsnakes but on my second go-around I have been having some trouble. Right now, mail is sticking in the postfix queue. I did find this error and am not sure what it means. "postfix/sendmail: fatal: display queue mode requires no recipient" Would this make sense of why the mail is not being delivered? Any help would be greatly appreciated. I am running Ubuntu 8.04 and followed the tutorial step for step as I did before and without issue.
