Mailsite

MailSite is a commercial mail server, calendar software, contact manager and collaborative software that was developed by Rockliffe Systems. It was one of the first mail servers to run on Windows NT using Internet standards when version 1.2 was released in 1996. Additionally, MailSite has been in continual development since 1996 with version 10 released in 2013, and runs on a single Windows Server as well as on a cluster of Windows Server computers. MailSite works natively with Microsoft Outlook versions 2007 to 2013 for mail, calendar and contacts without requiring any Outlook plug-ins, as well as including an Exchange ActiveSync (EAS) server for synchronizing mail, calendar and contacts with mobile devices. MailSite also works with Internet Standards-based mail clients such as Mozilla Thunderbird.
