Java Mail API: -->DB software manages the data in the form of DB table cols -->WebServer manages and executes web application -->JNDI Registry manages objects -->Similarly mail server manages and executes Email Accounts and Email Messages        Java App---(jdbc api(java.sql.javax.sql,...))---->DW Software        Java App---(jndi api(javax.naming and its sub packages))--->JNDI registry             E.g:- rmi registry, Cos registry...        Java App--(java mail api(javax.mail,javax.activation ))-->Mail Server            E.g:- james server, Lotus Notes, Microsoft exchange server Mail Server Architecture:- 1.)SMTP=Simple Mail Transfer Protocol 2.)POP=Post Office Protocol 3.)IMAP=Internet Mail Access Protocol --> Incoming server  receives and manages email messages in the email accounts --> Outgoing server  sends the email messages from one account to another account -->The  pop3  enabled mail server sends the em

Security:- a.)Network security (Network admins will take of this by using firewalls) b.)Web application security (Programmers should take care of it) (1)Authentication (2)Authorization (3)Data integrity (4)Data privacy (1)Authentication:- -->Checking the identity of a user is called Authentication.
