I recently had to entirely re-IP a network including the server running Spamassassin. When I run sa-update, it just hangs at the command prompt with a flashing cursor; same thing happens when I run sa-update -D but only after it calls the updates.spamassassin.org channel...
Checking my firewall logs, it appears sa-update is calling the wrong LAN IP of our Windows DNS server (I understand SA-UPDATE runs updates through DNS). I guess my question is where does sa-update cache or obtain this DNS address? Was it captured during the original nmake process? All other DNS requests from clients and or software resolve DNS queries just fine; no other DNS issues on this network...I was unable to find any reference to this IP in the sa-update.bat file. Running Spamassassin 3.2.5 on Windows Server 2003/Exchange 2003.
