    OCS Mail Server Architecture
    Sunday, July 01, 2007
    Register for R12 upgrade





    Mail Server is component of Oracle Collaboration Suite which is from Oracle Fusion Middleware Family.


    There are two main components in Oracle Collaboration Suite Mail Server
    i) Application Tier which consists of Oracle Mail Web Component and Oracle Mail Protocol Server
    ii) Infrastructure Tier consist of Mail Store (Repository for Mail Messages) and OID (Identity Store or LDAP server from Oracle) (* For more information on OID Click Here)

    Application Tier
    As shown in figure, Application Tier consists of Web Components (Application Server Instance – Web cache and HTTP Server and OC4J Instance) and Mail Protocol Server (POP3, IMAP4, SMTP-inbound & outbound)

    Outbound Mail Request flow (POP, IMAP) in above architecture
    i) Client (desktop clients like POP3 or IMAP4 or MS Outlook using outlook connector) in Intranet delivers send mail request to SMTP server.
    ii) SMTP server then sends mail request to OID to verify and authenticates recipients address and send mail request back to SMTP server.
    iii) If message recipient is internal, SMTP sends message to inbound SMTP server which deliver it to Mail Store
    iv) If message recipient is external, then SMTP server sends message to individuals

    Inbound Mail Request flow (POP, IMAP) in above architecture
    i) Mail from outside organization delivered to SMTP server.
    ii) SMTP uses OID for authentication and address verification.
    iii) This request then goes to SMTP server which then sends it to mail store for user pickup.

    Above two methods are NOT using web client, hence Application Server (Web Cache & HTTP Server) is not in request flow.

    Webcache , HTTP Server and OC4J are used only for Web Access of Mail Server.


    Installation of Oracle Collaboration Suite including Mail Server, RTC coming soon …
