I've set up Postfix to authenticate with SASL on a Ubuntu based system. I've done this by following along with some recipes, but mostly readying a lot of the docs.
One bit that works, but which I don't understand how it works is based on a recipe from the postfix website. I have created the file
/etc/postfix/sasl/smtpd.conf, which I understand is a SASL, not Postfix, configuration file. How does SASL know to check this location for config when working with Postfix? I didn't have to configure SASL to point to this directory, so is it hard coded? Are there any other directories will SASL search in for config?
