I'm new to Linux, but I'm slowly finding my feet.
Sendmail 8.12.8, Redhat 9.
I want to setup sendmail so that it requires a username and password in order to send mail through it.
Basically, I travel around a lot, and I use a lightweight Windows pop3 client (popcorn). I need an SMTP mailserver to use to allow me to send emails when I'm on the move (and could be connected to any ISP), so I figured I might as well use my own!
Can anyone advise me as what's best? Obviously I don't want my mailserver to be an open relay, but I need to be able to use it to send mail from the internet.
Please bear in mind my Linux skill level (0.5 / 10) when advising.
