"It can be used by any corporation to handle their enterprise email."BrothersoftEditor: Xeams is a free email server that can be used by any corporation to handle their enterprise email. It works on any operating system and can handle unlimited number of emails and domains. Xeams can work in 3 modes:Stand alone server - In this mode you do not need any other email server, but Xeams, to handle every e-mail. Clients Connect to Xeams using POP3/IMAP protocol to fetch their messages and use SMTP to send out-bound emails. Spam firewall - In this mode Xeams sits in front of another email server, such as Microsoft Exchange, Sendmail, Novell Groupwise or any other SMTP server. Every in-coming email filters through Xeams and only good messages are forwarded to the actual email server. Your users connect to the corporate email server to fetch and send email. Hybrid mode - This is a combination of mode 1 and 2. Using Xeams in this mode provides redundancy to your existing email infrastructure. Every message is saved in two places: Xeams and your corporate email server.
