You could do with something to execute this filter:

(&(objectClass=contact)(!(targetAddress=*)))

That gives you all contacts which have not been Mail-Enabled in any version of Exchange from 2000 up.

Options for executing that include:
# Quest - http://www.quest.com/powershell/activeroles-server.aspx
Get-QADObject -LdapFilter "(&(objectClass=contact)(!(targetAddress=*)))"

# MS AD CmdLets
Get-ADObject -LDAPFilter "(&(objectClass=contact)(!(targetAddress=*)))"

# Native .NET
([ADSISearcher]"(&(objectClass=contact)(!(targetAddress=*)))").FindAll()

Open in new window

And if you're running Exchange 2007 or 2010 you can also do this:
Get-Contact -RecipientTypeDetails Contact

Open in new window

Of course, you can use the LDAP filter in any other program able to search, such as AD Users and Computers, or ADFind, or, well the list is pretty much endless.
