I am running MAMP Pro on my machine with all empty Postfix values. Yet, whenever my PHP application calls mail(), mail is being sent out from my machine. In a production environment this would be fine but I am in a development environment. how can i disable outbound mail in postfix? discusses setting the default_transport = error. However, this setting does not appear in /private/etc/postfix/main.cf, additionally, I cannot verify that this is infact what I need. I want to be absolutely sure that mail is disabled. I do want to be able to receive mail from my Entourage client but that's it.
Can anyone help? Many thanks!
