I use Razor in conjuction with SpamAssassin on my home computer and I have two ports open in the firewall as prescribed 7, 2702 and 2703 but cloudmark.com is also, according to the logs, trying to access many other ports such as 5272, 5321, 5273 and so on.
According to the SpamAssassin destructions, if you're using the DCC checks you'll need UDP port 6277 open:
"Also note that DCC requires that you open your firewall for DCC reply packets on UDP port 6277. DCC uses UDP packets when replying, which are blocked by most firewalls by default. As a result, it requires that you open your firewall for DCC reply packets on UDP port 6277. Here's sample firewall rules required:
allow udp local gt 1023 to remote 6277 allow udp remote 6277 to local gt 1023"
Try running "cddc info" from the command line.
I don't have any other unusual UDP ports open and my TCP ports are the standard usual services apart from some slight unusual ones in the higher range reserved for use with cPanel which is running on my box.
