After installing sendmail , you should configure sendmail. It`s little hard. But don`t worry after that we can spoof email to anyone.

Type following command on terminal

It will open sendmail.mc file.

For example your last two lines are as follow

MAILER(`local')dnl

MAILER(`smtp')dnl

Put this code before that two lines.

define('SMART_HOST',`smtp.gmail.com')
