postconf -e 'smtp_sasl_auth_enable = yes'
postconf -e 'smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd'
postconf -e 'smtp_sasl_security_options ='

chown root:root /etc/postfix/sasl_passwd
chmod 600 /etc/postfix/sasl_passwd
postmap /etc/postfix/sasl_passwd
/etc/init.d/postfix restart
In /etc/postfix/sasl_passwd you put your ISP's SMTP server and a user name and password that are allowed to send through that server:

Code:   Username on
Whenever you change /etc/postfix/sasl_passwd you have to do the following:
postmap /etc/postfix/sasl_passwd
/etc/init.d/postfix restart
Now if you want to send email from your XP machine you tell your email client to use the user sampleuser with the password samplepassword along with your internal SMTP server (
