How to setup a Mail Relay in Postfix?
Follow the guide below to configure Postfix to use outMail as a Internet Mail Relay.
This article already assumes your Postfix system is able to send emails externally and that you are already have a terminal connection to your server with the necessary access rights to manage and administor postfix.
First you need to create a password file for postfix to use. Create a file called /etc/postfix/relay_passwd and add the following lines to that file
where OUTMAILUSERNAME and OUTMAILPASSWORD are the (case-sensitive) information provided when you set up your account.
To enable postfix to use the outMail service at the prompt type the following
postconf -e relayhost=mxXXXXXX.smtp-engine.com postconf -e smtp_sasl_auth_enable=yes postconf -e smtp_sasl_password_maps=hash:/etc/postfix/relay_passwd postconf -e smtp_sasl_security_options=noanonymous postconf -e smtp_sasl_mechanism_filter=plain,login postmap /etc/postfix/relay_passwd
For the above changes to take effect the postfix service will need restarting (service postix restart)
