[users@httpd] mail()

[Hiep T. Nguyen]

Hi there,   I just wonder if I need to setup email server (postfix,qmail,sendmail) in order to use mail() function in php?  If not, what do I have to configure for mail() function to work properly?   Currently, I'm using CentOS 4.2 and I'm not hosting my own email server.   Thanks, JC
