I am trying to send mail using PHP mail() function. I have install postfix, modified all of the required files as suggested by the Ubuntu help docs.
I also changed my php.ini file to set the path of the sendmail_path to sendmail_path = "/usr/sbin/sendmail -t -i" but still I cannot send mail to my hotmail account or yahoo or gmail.
Edit:
Stop down voting me ; even I do not know my problem . All I realized so far is that my ISP is blocking every port except 80 . If any one can help me mitigate that problem , it will be my pleasure .
