I require some advice as to how to set up Redhat 4.2 for multiple email and web hosting. I have set up Apache virtual web hosting (multiple IPs) and it works fine. The problem I have is setting up mail services.
What I need is POP3 and SMTP but I also need to set up accounts for one or two domains so that they can pick up *all* their mail.
In other words, we have customers who pick up mail on an individual basis using Netscape, but other customers who use TFS gateways for their whole domain.
What sort of configuration do I need on our server? We have used QPopper and QMail in the past to overcome security issues, but I understand that Redhat 4.2 has secure mail now.
I am told I need a store and forward server for the customers who want to collect mail for their whole domain.
Note: we are connected 24 hours, the customers TFS gateways are not and just poll every hour or so. Ideally, I would like to put all the mail services on a single Linux box.
There are many email servers available, do I use the products that come with Redhat 4.2? What is the most flexible configuration of products?
Your help is much appreciated.
