I checked the Verify MAIL FROM address and I still get messages sent
from invalid accounts on my domain. I do not have a nobody alias. I
restarted the QM and SMTP services after the change....any ideas?

Subject: [IMail Forum] Block messages that claim to come from my domain
Is there a way to block all messages that are "from" my domain but are not
valid accounts or aliases setup in my domain? We've been getting a lot of
infected zip files lately that are claiming to come from email addresses
that don't exist in our domain. I realize that I can just explicitly block
those that I've identified, but I want to know if there's a way to block
future ones as well without explicitly knowing what they are.
Thanks,
