With Intranet/Extranet Mail Server, everyone in your organization or network of organizations can have their own Intranet/Extranet E-mailbox. If you have a company's Internet E-mailbox with unlimited E-mail addresses for your staff (anyname@yourcompany.com, for example), this software can manage and distribute mails right to your staff's Intranet/Extranet E-mailboxes. Also it distributes mails from Intranet/Extranet E-mail accounts to Internet E-mailboxes. This software works well with the Proxy Server.
