Yes, this works.  The tricky part is to do the configuration tweaks.

In a nutshell:
You need spamc on the server where horde is hosted.  Then within  
horde, one of the configs is: "/usr/bin/spamc -d <SA.server.net> -L  
spam -u %u" (when using realms this gets somewhat more complicated).
Then on the SA server you need a few more options for spamd:  
"--allow-tell --ip-address --allowed-ips=127.,<your horde server IP  
addr here>"
