Hi ,
I'm developing a mailing system inwhich I'm using php and qmail at the backend . There are different users on the mailing system .
I want to give facility to my users to change their passwords. When i tried to use the system command
system("filepath/vpasswd $USER_NAME $new_pass");
then errror message of "illegal username" displayed .
Plz tell me the way how can i give facility to my users to change their passwords .
Thanks in advance
