To be perfectly honest you probably don't want to put a rule like that in any firewall anyway. The only way to allow it to do something like that is to pull a DNS zone transfer to get the list of all hosts in that domain and then build the ip rules from there. Firewalls are ignorant of DNS in general so all DNS names are translated to IP to apply the rule. Most DNS servers will not allow just anyone to pull a DNS zone transfer so this would fail most of the time.
This is not a permanent solution but might help you right away. You could figure out what ip or hostname the software is connecting to for this software to work (protocol decode or check shorewall logs to see what is being blocked from this machine). Then after that add the rule bu IP or reverse DNS or do an the IP to get the hostname (might work might not).
