If you simply want your server can send mail to the outside, you can use sendmail application. Once installed and configured, you can use the mail() function of PHP to send mail.

Install sendmail

Code:
sudo yum install sendmail sendmail-cf
Configuring sendmail

Code:
nano /etc/mail/sendmail.mc
Note not edit sendmail.cf file because this file is automatically generated from sendmail.mc file

Configure DAEMON_OPTIONS to allow sending mail from localhost/smtp

DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

Edit LOCAL_DOMAIN to hostname

Code:
LOCAL_DOMAIN(`example.com')dnl
Update sendmail configuration

Code:
sudo make -C /etc/mail
Restart

Code:
sudo service sendmail restart
Check sendmail

Code:
echo "Subject: your subject" | /usr/lib/sendmail -v [email protected]
In order to facilitate the sending of mail, you should note hostname in CentOS install exactly.
