On linux, I use exim4 to send mail to a public email address. I don't have to authenticate or anything. It pretends its [email protected] and sends it to [email protected]. Is it possible to do the same on OS X?
I have a cron job, and I want to send mail from the root user as [email protected] like with my linux box. I looked up postfix configuration as it seems to be the method used, but all the examples require authentication. Is there anyway to avoid this?
