freshclam uses DNS (port 53/udp ... and you should open tcp too,
perhaps) to check current versions on the cvd files, and use HTTP
(port 80/tcp) to download them, when needed. I imagine (not at a box
ATM) that the phishing whitelist is gotten with a wget or curl, which
implies HTTP...:-). Spam list .... Is that "updated"? Checking RBLs is
done via DNS, so .... that's back to port 53...
Note that you only need these "from the inside->out", so to speak.
