Blocked and allowed senders
You can add to the list of blocked senders the addresses, mail from which Anti-Spam will recognize as spam. Sender addresses from which you expect no spam are stored in the list of allowed senders. The list is created automatically during Anti-Spam training. You can also supplement the list manually.
You can add to the lists of allowed or blocked senders complete addresses or address masks.
