What is the difference between OCS, Webmail, Thunderbird and IMAP?
Oracle Collaboration Suite (OCS) was Macalester’s e-mail system through the end of March 2008. E-mail sent to and from Macalester e-mail accounts was handled by OCS. The main interface for OCS was on the Web, and was called ‘Webmail’ or ‘OCS Webmail.’ Many people at Macalester, including most students, used only OCS’ Webmail interface. Faculty and staff mainly accessed their OCS e-mail through Thunderbird, a desktop mail client made by Mozilla. Thunderbird was very popular since it handled e-mail with more elegance and better functionality than OCS Webmail. The connection between OCS and Thunderbird is an email transfer protocol called Internet Message Access Protocol (IMAP). IMAP is a technical specification rather than a product, and other e-mail packages (including Google Apps) support it.
