I am building a web server on which I want php to be able to send email to clients. I installed Debian Sarge (netinstall cd) with Apache2 and followed your instructions (FalkoTimme's) on inserting php4 and php5. However when I add the following to the apache2-default.conf apache will not restart. If I comment these lines out Apache restarts okay. FYI- I am a Debian newbie.
What's in the Apache error log? Did you follow the tutorial as close as possible, or did you do some modifications?
