Hugo, thank you very much for your response. I only changed them to SUID for testing purposes and then changed them back immediately. Yes SUID == BAD, agreed. I might not have been clear. The nagios process is running on a separate dedicated box which I'm using (hopefully) to monitor the queue on my /other/ qmail server. Am I not understanding correctly? I thought that was the purpose of the check_mailq plugin, no? Maybe I need more basic guidance? ------------------------------------------------------------------------- Take Surveys. Earn Cash.
