Good morning everyone!!
I have been charged with setting up an email server for my company. I last did this in (gasp) 2000 with qmail on RedHat (I think 7.1 at the time).
Anyways, I have sort of settled on CentOS as the OS, and Scalix as the email system.
To be efficient, I want to set it up so my users connect to it over the LAN when they're at work. Of course, it will need a NIC to the DMZ of my PIX firewall so the outside world can send us email. So my question is, how do I set it up so it has that outside interface, but reduce the chances that someone comes in on that outside NIC and gets access to my inside network??
And if you have any recommendations on Email servers, feel free to tell me that too!!! I have my reservations about Scalix, though the web interface is very snazzy.
