I suggest you read this :- http://wiki.centos.org/HowTos/postfix

A static IP is not strictly necessary, but most would advise you are better off with it. I ran a private (non-commercial) mail server for several years using dynamic DNS and a non-static IP address. It was fine for me, but it wasn't a critical system.

Here is a link to another, very popular, how to document: http://flurdy.com/docs/postfix/

Setting up a mail server is not a trivial task but can be a very rewarding experience. Good Luck.

I haven't tried to install and configure LDAP, so I can't offer you step-by-step advice. However, the warning message is pretty clear: there is a DB (database) configuration file that is expected to be at /var/lib/ldap and it isn't there. The location of the file is likely configurable via the --configure command at build time. If you installed LDAP via your package manager, I would be surprised to have a missing file like this, unless you failed to perform a necessary installation step.

Also, does this question have anything to do with your post on 8-16 regarding a mail server? If not, you should start a new thread or better yet, report your post and ask the moderators to move it to a new thread.

You can setup and run a mailserver with just a static IP. I suppose it will work with a dynamic IP as well.
The problem comes in when the other mail server is or is not configured to ask your mail server for your
MX and reverse PTR records. And if you do not have reverse PTR and MX records, the remote mail server will
not accept your mail, and that email will bounce. If it does not ask for your MX or reverse PTR records,
the mail should go thru. The "may ask" depends on how strict the remote mail server is configured.
