Exception

You can allow or block emails from specific senders by specifying their email addresses or wildcard addresses.

Allowed email addresses: Enter an email address (abc@example.com) or a wildcard address (*@example.com). The firewall won't mark emails from these addresses as spam nor quarantine them. However, it performs antivirus scanning.

Blocked email addresses: Enter an email address (abc@example.com) or a wildcard address (*@example.com). The firewall quarantines emails from these addresses.

Note

If you list an email address or a wildcard address on both blocked and allowed lists, the firewall blocks emails from the addresses since the blocked list takes priority.

Allowed and blocked email addresses.
