I am a novice Linux server admin (I can us SSH, vi, cron, and understand config files), but I am willing to learn. However, I do not have hundreds of hours to research and learn all the ins-and-outs of Linux. I need something fairly turnkey:
What is the best server software that will do all or most of the following:
- POP3 server
- SMTP server
- Webmail server (with good standard features, like WYSIWYG editor, attachments, etc.)
- Web-based end-user configuration tools
- Anti-virus
- Anti-spam (blacklists and whitelists & RBL support required, spam filtering logic a plus)
- Authentication data stored in a database for easy management.
- POP-before-SMTP authentication
Similarly, I need to pick the best Linux OS to run this puppy on. I would like an OS with a wizard install, and one with adequate security for a publicly accessible server.
Last of all, it would be great if all of the above would be freely available for commercial use.
Thanks for your help!
