Hi all,
I was going through an evaluation of firewalls, starting with IBM firewall.
When coming to spam prevention (which can be a firewall's job since
unstopped spam can result DOS attacks, rite?), I realized there are a few
methods:
-restrict by IP address (but IBM firewall does not allow you to specify
"all-but-certain-IP-addresses")
-restrict by Domain names (IBM firewall does not have any such feature
documented)
-restrict by Key words in mail (IBM firewall does not have any such
feature documented)
Did I understand IBM firewall properly or is there any other firewall that
does spam prevention?
Thanx in advance.
