sendmail, iptables and security
i have a few questions. I am using red hat 8.0 and trying to host my own web page and mail server.
1. I want to host my own mail server, do i need virus checking on the Server?
2. How do i make the changes i made to iptables stick? They seem to flush out after a reboot
3. How do i create a new mailbox for a user using sendmail?
4. How do i setup my windows 2000 machine to accept mail through the mail server?
5. What do i need to do to secure my web and mail hosting server? Any good reference sites i can look at please?
