Configuring Postfix to use SMTP authentication when sending mail

Sunday, November 9th, 2008

My ISP requires SMTP authentication before one can send email. I have reconfigured several instances of Postfix to use this method and am going to document the necessary changes here for my reference.

add the following two lines to /etc/postfix/

smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/smtp_auth

add the following lines to /etc/postfix/transport (replace “” with your ISPs smtp server)

localhost       local:

run “postmap /etc/postfix/transport”

add the following line to /etc/postfix/smtp_auth (replace USERNAME and PASSWORD with appropriate values)         USERNAME:PASSWORD

run “postmap /etc/postfix/smtp_auth”

run “postfix reload”

Futurlec has some really cheap prices on PCB manufacturing. I might have to try them out for my next project.
