You're saying here "Block senders listed in sender_domains AND sender"
Seperate the acl.

Just a guess, you weren't using an address that's listed in both files.

But test@??? is not in the "sender" file, right?

This makes the format of the file different. Instead of listing each
address sperately like:
test1@domain1
test2@domain1
test1@domain2
...

It would look like this with @@learch* :
domain1    test1:test2
domain2 test1:test2


the * at the end makes it lookup the domain * if the domain isn't found.
It's basically in the format:
domain    sender1:sender2:sender3:...:sendern


I use this format. It makes the file smaller. Each sender can be a regexp.

See above. Use 2 acls.
