Ownership of Directories/Files under /srv/www/htdocs

OS: SuSE 10.0 Pro I recently installed PostfixAdmin 3.1 doing the install as root and changed file permissions to 640 per the instructions. However, I cannot access it unless I make the files world readable (644). Question: What owner:group should applications be installed as under /srv/www/htdocs? I currently have phpMyAdmin and PostfixAdmin. Thank you, Lucky Leavell
