How to Setup Centos for Procmail or Fetchmail
Procmail and Fetchmail are two Linux mail programs that can be installed on the CentOS operating system. Both of these operating systems are installable through the "yum" software installation software, but only one should be installed at any time because they can interfere with each other if they are both installed at the same time.
