I'll soon be setting up a little in-house network with a Apache, an FTP server, and a mail server. Unfortunately it's windows based. I'm happy with Apache, and Serve-U, and I'm currently using Mercury Mail Server with good success. I would like to explore my options as far as mail servers go: I want to have server level spam and anti-virus checkers. Can someone recommend a free/inexpensive mail server that's robust, reliable, that allows me the kind of flexibility I would like... and hopefully doesn't have a hellish learning curve? What do you like? It doesn't really need to be enterprise level--just solid. Thanks. -- Frank Marion lists at frankmarion.com Keep the signal high.
