I have a server with a dedicated IP. I didn't take any domain yet. CentOS 6.2 is installed on this server. I tried to install mail server in it and followed these links exactly.
Everything is installed perfectly but my questions are:
- How do I create mail id’s and where?
- Where is my main mail panel?
- How does the mail system work and how to manage it?
- How to make mail system secure and customized?
- How to make my IP address swap with a name e.g. mail.something.com not IP?
- Can I use only IP to send or receive mail with this mail server?
I need to install mail server for my small group of 50 people and this may increase in time. I need the full installing guide of mail server from A to Z procedure.
