how do i remove domain email aliases using a cmdlet in exchange 2007?

can you elaborate more on what you are trying to achieve?

each user has default domain aliases as well public email aliases e.g. admin@contoso.local marketing@contoso.local marketing@contoso.com where marketing@contoso.com is a valid alias, so how do I get rid off other two.
