title: CentOS, mod_evasive log write permissions and email issue
body: <p>i'm on CentOS 6.5 now, 
  installed mod_evasive some time ago but email notify and logging never worked...</p>
  
  <p>into messages log i have many lines like this...</p>
  
  <pre><code>mod_evasive[4548]: Couldn't open logfile /var/log/httpd/evasive/dos-157.xxx.xxx.xxx: Permission denied
  </code></pre>
  
  <p>on CentOS I thought that the owner of the directory /var/log/httpd/evasive should be "apache" and that is with 755..
  no way...</p>
  
  <p>then, mailx is already installed and updated... someone says to see into mod_evasive20.c but i can't find this mod_evasive20.c file on my CentOS... where can be? is it possible to send with sendmail instead of mailx? thanks</p>
