is there any mail server in microsoft server 2008.
The SMTP (mail) server is still there in Windows Server 2008, but it is less obvious to install and to configure it since Windows Server 2008 ships with IIS7, and SMTP server is configured through IIS6 Manager.
Installing the SMTP service
To install the SMTP service, go to Server Manager and expand Roles and Features.
In Roles, right-click on Web server (IIS), and click on "Ad Role Services". Add IIS 6 Metabase Compatibility and IIS 6 Management Console (both in Management Tools -> IIS 6 Management Compatibility).
In Features, open Add Features Wizard and search for SMTP Server in the list.
Configuring SMTP service
To configure SMTP service, start Internet Information Services (IIS) 6.0 Manager (typing "IIS" in start menu works well). In the tree on the left, you will find your server, and inside, [SMTP Virtual Server #1].
Do not expand it, but rather right-click on it, and choose "Properties". You will find everything you need here.
