Postfix mail server setup questions
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 be able to connect to the server to retrieve mail for the accounts. I've done some research on how to set up the majority of the options we need in the main.cf file, but wanted to go over just a few things:
1. How exactly do I set up the individual email accounts for login? Do I need to create them within Linux first, then add them to the alias file?
2. Assuming Groupwise will work, it requires an IP and port number to connect with. The IP is no problem, but if there someplace to specify the port to all incoming connections to retreive mail?
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. Anything else I should need installed to get this to work? Other than setting up the main.cf and the alias file, is there anything else server side I would need to do?
Thanks a lot in advance for you help.
