Sorry it is almost mid-night here and stuck at office.
I have a sendmail relay at DMZ, the access.db in Sendmail can block the
entire domain. I do filtering at both at Exchange and Sendmail.
You are right may not be able to block entire domain in Exchange.
Just saw the article can use wild card?
*@*.domain.com ? I am not sure did not try this out.

Where is the configuration to filter out entire domains?

The From field can be faked. Normally for me I open up the mail in
Outlook click on "View" and go to "Options" to look at the
email envelope. You should see which smtp server that is sending these
junk. For me I just block the domain from the smtp address.
Not foolproof, one time I actually block a ISP in UK.. Ha Ha .. and my
user scream at me because her brother is using that ISP...

We use the built in exchange filtering quite heavily to block the tons
of garbage email we get. Adding 5-10 new filters every day is a pain,
but its worth it in the long run.
yesterday I received a new group of junk mails from a source labeled
as.. [%%email.addr%%]
How do I add this kind of completely invalid email address to the filter
list... and isn't exchange supposed to weed this invalid garbage out
anyway?
There is no @ sign in the address so I have no idea how to label it in
the filter list.
Thanks
