Question Postfix setup questions

Normally I don't like posting in 2 different sections, but I'm hoping someone here will know something about this...

I'm looking to try and set up a Postfix mail server on a RedHat 9 system. Ideally, I'd like to have Groupwise 5.5 (should be Pop3) be able to connect to the server to retrieve mail for the user accounts. I've done some research on how to set up the majority of the options we need in the file for postfix, but wanted to go over just a few things:

1. It sounds as though I need to have something else installed in addition to postfix to actually do something with the mail and set up the users accounts. Anything recommended that's easy to set up?

2. In order to get the ipop3 and/or imap services running, it says "You must enable xinetd to use this service." Of course, xinetd is already running. I've adding ipop3 through the services window and with chkconfig, but the status always stays the same. Is this normal, or should I be able to manually start and stop this service? Anything I need to do to xinetd to get it working?

3. Anything else that may be needed to get this setup to work? This is running on a newly installed and updated install with the most recent version of Postfix, and I downloaded Courierimap as well, although that doesn't want to install. A single program to run the server and control the users would make things much easier if such a thing exists.

4. Any good thorough tutorials out there? I'm really surprised at the lack of documention on setting up mail servers. I would think that someone would have a write-up from start to finish of setting up the server and services, then the users, and finally testing it out.

I'm really stuck here though, so if anyone can help, I'd really appreciate it.

I can help a bit.

1. Setting up user accounts can be accomplished in one of two ways. Either they must be made a local unix system user, or you must setup virtual mailbox hosting using some form of a backend(ldap, sql, db3, etc...). It's up to you to choose. The easiest is to setup local user accounts, but unfortunately it's the toughest to administrate since you have security concerns to worry about with more users on the console of the box. Virtual is my choice using a mysql backend.

2. I assume postfix is running standalone? If you've added your services to the /etc/xinetd.d/ directory and /etc/services file and it's still not running then the command set you're using is probably invalid. Make sure you haven't fubar'd a switch or accidentally set it to disable, or something small like that.

3. There is no all in one solution. Love it or hate it this will be the culmination of at least two, if not 3 applications. Postfix for SMTP handling, 3rd party for pop3 and 3rd party for imap.

4. is the howto I used to setup my virtual hosting. It's obviously gentoo centric, but shouldn't be too tought to muck through getting the sources compiled. You obviously don't have to use everything they suggest, but it's nice to have all the frills working.
