i m very thankful to u on giving this fruitfull information. pls  u pls tell me more abt  MS exchange server  and lotous mail  are they supported with jsp.

is there any server like these (exchange/lotus mail)offered by sun/java .

Dear hamid,

i've to offer mail  service just like an isp offer. for this purpose i found SIMS ( sun internet mail server).

this server  offering all the features which i was looking.

take care and must share information.

sometimes back I used Argosoft's mail  server. It comes
with already developed application, from which you can
see emails through browser.

company address is: http://www.argosoft.com

This mail server  is quite light weight and able to do
everything you want with mails.

can i used it without static IP or i must required an static IP.
I have my own website  like http://www.myname.com
can i use this as domain. will this effect on existing mail  server.

I too used it at NT server  without any static IP or
domain name. You Computer name will be your domain
name.

1 ) If u want to write a Mail server  by java there are
some ways :
a) Socekt Programming
b) using Java Mail API
c) ...
in first item , u must know somethings about SMTP or
ESMTP and POP3 or IMAP
and then implements them on ur server.
but sencond item is better for u.
2 ) JSP Technology is not suitable for writing Mail
Server(it is better i tell that is not possible)
but u can use it for N-tier Mail web based application
in bussines layer.
HTML page <----> JSP page <-----> Mail Server
User Interface Layer <-----> Bussines Layer <------>
Data Store Layer
