Receive email to certain addresses from internal domain only

Hello,
I'm trying to figure out how to receive email from the internal domain
for certain addresses. In other words, we have some staff alias
addresses that just need to have internal email, and no spam from the
outside.

For example

an alias allstaff [at] domain.com sends to a list of all of the staff

If someone sends out and email outside of the domain with this address
included, it's not very long until all of the staff are slammed with
spam. Then I have to change the allstaff alias to something else.

If I can get sendmail to accept messages going to this account be only
from our domain, and maybe one other domain, life would be a lot more
easy.
Thanks
Dale
