upgrade, but right now it isn't possible.

Im trying to block spam (for instance, from
As far as I know, it's trying to pass as a message from my very net:

For other details, see the local mail logfile

but the MTA correctly rejects it as a fake.

I have created an alias list (rechaza) in the menu Firewall/Aliases,
where I put all the addresses known to be spammers, and tried to reject
them with the rule in Firewall/Rules/WAN

Action: Block
Interface: WAN
TCP/IP version: IPV4
Protocol: TCP
Source: (single hots or alias) rechaza
Destination port range: any

but I can not stop the spam right in the WAN interface.

How could I create a convenient rule?
