Hi,
no results .. either email or fixed domains escaped into the inbox.
In that case, you have configured to receive all emails in catch-all under Mail home of that client.
If you set the catch-all to delete, then the emails will get deleted and not diverted to an Inbox.
Such a configuration, what you have, can be really troublesome.
If the spams arrive through spamdyke, then you did not configure spamdyke properly. You should read instructions in this forum on how to configure it.
Also make sure to update the spamdyke to version 5, the latest, and make changes in spamdyke.conf.
Then, the spams will stop. This will 100% work to stop spam emails 99%!
