I wanto to put a an email server at my company but I lack some of the experience regarding this function (I usually used just web in the past). I want to know how to set up an email server from scratch so I start reading the manuals and I end up with a bunch of specific questions, hope you guys can help me out:

- Do I need a static IP or can a DynDNS service help me out?
- What are the basic information every postfix email server will need and which is not required but recomended.
- When is relay necessary?
- What are the threats to building an email server (attacks, exploits)?

Can someone tell me what files/lines will I need to configure on all this questions. Regards.

Hey Jzarecta,

My best advice would be to get a static ip address becuase a lot ISP's out there block domain names that have a dynamic ip addresses. I know this from experience because I had my email server running with dynamic DNS for over 3 years and I got tired of my emails getting blocked so I switched to static ip's about a month 1 or so ago now everyting is fine.

wow nice answers, just wonder if you can answer some of my basic questions like:
- mail server basic options

For example if this was an apache server the basic requirements will be DocumenRoot, ServerRoot, and a very recommended optins will be Loadmodules etc
Can you please comment on these?
