I believe that this option is supposed to be available now.
what I am after
I have an email domain @domain.com
I want emails going to email@example.com to go into gregs mail box
I want any email going to @domain.com that does not match greg, or sam, (or other defined mail boxes) to go into the mailbox for firstname.lastname@example.org, a mail box that I will give ownership to a group within Windows 2003 server, so that it can be monitored by the helpdesk of this client.
any suggestions or answers?
