I'm looking for a replacment mailserver for Exchange server 5.0. I've looked at Qmail, Sendmail, Openmail and Postfix
While they are all kinda easy to install (except Openmail) I fail in the configuration terribly. I'm to used to the gui crutch of configuring Exchange server. I've yet to set one of these up and be able to connect to the server from a client machine.
How's Courier compared to the above in installation and configuration? How about client connections? My clients use MS Outlook and Outlook express mostly. Is anyone using Courier as a domain mail server?
