virtual mail using sendmail

Dear Friends ,
I have a mail server in Redhat Enterprise 3 using sendmail.
Let it's domain is : "example.com" . I want to make another
virtual mail server which domain will be "mail.example.com"
Is it possible to do it using SENDMAIL ?If it is possible then
plz help me how can I do it ?

Yes, use /etc/mail/virtusertable to map virtual users to real mailboxes on the system. This link has an example. I've used virtusertable combined with aliases to set up truly virtual users, e.g.:

in /etc/mail/virtusertable

Code:

foo@my.virtual.tld myvirttld-foo

in /etc/mail/aliases

Code:

myvirttld-foo: /var/spool/vmail/my.virtual.tld/foo/mail/inbox

Then you can instruct your POP3/IMAP server to use /var/spool/vmail/my.virtual.tld/foo/mail/inbox as the inbox for user foo@my.virtual.tld using whatever configuration method is appropriate for your particular server software. This may be more complex than what you're looking for if you just need the virtusertable to associate an address with a "real" system user (i.e. one with an entry in /etc/passwd).
