I'm receiving too many spam from different sources ... how may I block this ??
In the Sender Blacklist, I can put email address or domain names .. but, what about they are fake e-mails or domains ??
Is there any option to block by IP or network ???
I was trying to add a new network definition, but its very hard to do, because I need to add a new definition by every host or network ...
A good option could be, create a 'Spammer' network definition, and put there all the IPs or networks to be rejected or drop in the Packet Filter section ...
Regards ...
