firewall ports needed for spamassassin

[Kevin J. Steil]

You will need to open SMTP ports, both inbound and out (optional)
(tcp25)
You will need to open port for Razor (tcp2703)
You will need to open DNS ports (tcp/udp 53)
You will need to open SSH or other ports for management of the server if
in a DMZ (tcp22)
You will need to open HTTP and FTP outbound so that you can you update
the server either using perl -MCPAN or browsing to download software and
using mget...(tcp80/443 and tcp21)

SpamAssassin will be doing a load of DNS lookups, using whatever machine
is
referred to in the /etc/resolv.conf just like all other DNS lookups
(someone will correct me if I'm wrong).

So it needs to be able to access a DNS server which can do TCP+UDP port
53
to the outside world (note "to" not "from", you aren't creating an
inbound
hole).
