As best I can tell, we have no firewall restrictions blocking intranet
packets at all.

Oh, no, I didn't mean to give that impression.  I am fully ready to take such
connections as far as I know:

/usr/bin/spamd -d -q -x --max-children=5 -H /etc/razor -u maildrop -r
/var/run/spamd/spamd.pid -i 10.10.10.170 -p 2054 -A 10.10.

Even if I had forgotten the -A, I think I would have been seeing connection
refused notices, but right now, it just seems to time out.  I'm pretty sure
this is a LVS question more than a spamc/d question, since I've no problems
with the latter -- I am only asking here to see if anyone else does SA
weighted load balancing.

Thanks!
