Hi , I am having Windows 2003 Server installed , yet i have not installed exchange 2003 . my live web site is also running on this server. Now the problem is i am going to give sub domain from my parent domain website .. e.g My Parent server is xyz.com Now i am creating 100 sub domains daily like abc.xyz.com , pqr.xyz.com etc ...I need to create a mail id for each of this sub domain e.g john@abc.xyz.com , phil@pqr.xyz.com , you can say 2-3 mail ids in each of the child domain ...but the thing is i am going to create numbers of domains daily for my web site ..as i am having one web site and i am going to allow users for the sub domains...is it possible if i am installing Exchange 2003 in a Parent server only ..not in all the child domains ..as my all the sub domains will be hosted on parent server ... Please Help .. John

Hi Exchange experts , Can anyone please help me to solve this ... John

As long as you have MX and A records for all the domains, and have a receipt policy that contains each, it should work. My last company had 18 different e-mail addresses. Thanks, John G.
