ThreatBlock v2


Available as a basic part of the upcoming UTMv2 firewall and for all other installations on request, the ThreatBlock concept is evolving.

There was the problem that the initial communication did not get closed, so I had to switch to tcp-reset e.g. by doing

sed 's/icmp-port-unreachable/tcp-reset/' /etc/4ctual > 4ctual_RESET

Also, some more qmail variables should be closely watched and eventually adjusted, e.g. timeoutsmtpd and concurrencyincoming.
