POSTFIX -securing [slackware]
Greetings. I've just installed postfix so that I can send and recieve mail from my personal desktop machine. I want to implement some basic security.
I have to stress at this moment that I've never installed or configured an MTA.
Basically I'd like it so that only my admin account (markzero) can send mail from this machine. Also, I'd like to make this a client only (no mail sent from anything other than localhost). I'm using the default postfix install on my OSX machine and a nessus scan reports that no smtp server is listening on any port, I'd like to duplicate this on my linux machine.
