Thread:Project:Support desk/PEAR not detected

I am trying to set up SMTP so I installed PEAR mail and all corresponding modules (Auth_SASL, Mail, Net_SMTP, Net_Socket) to folder /home/php/. However, this is not where php is installed, because php is installed somewhere in the background of the server. When I try to send mail via SMTP, I get "PEAR mail package is not installed" error. Do I need to set path to where PEAR is installed? If so, how? Or should I install PEAR in my wiki's folder? Tanks.
