I am a Linux noob and have installed Fedora Core 6 and am having a problem with my LAMP install. When trying to install Postfix, one of the steps is to stop sendmail and this fails ... /etc/init.d/sendmail stop failed From what I have seen elswhere online, I believe this is a necessary step and the probable reason why the later step - telnet localhost 25 - is refused (correct me if I am wrong please) How do I stop sendmail? Is there another command I can use? Everything else is working fine with the LAMP except postfix. I have ispconfig up and running and it works fine except for the webmail - because of the postfix problem I am assuming. Thanks for your help!
