mailing concept

Hi everyone. I just took up a project on mailing system, i just need to create a replica of Microsoft's outlook or even like open office , now that designing part is over, am concerned with the way in which we send and recieve mails,

SO, can anyone guide me in depth on concepts such as sending and recieving mails and its implementation.

dude.....i also need the same code.if u get fwd it to me./

Here is place to start:

JavaMail API - FAQ

This is mostly what you need for sending/receiving mail
but advanced options in commercial e-mail clients are not something
you can find there.

So read it all and pay attention on what this API is NOT for.

good luck!

Thank you FON.
