I think that's fine. I have a similar system and get

               total       used       free     shared    buffers     cached
Mem:         94196      82012      12184          0       4648      19356
-/+ buffers/cache:      58008      36188
Swap:       136544      24356     112188

Linux uses all memory it can for disk caches which it frees if more
program memory is needed. So a Linux system which
has been running for a while ends up with nearly 100% memory usage.

To get a better image, you may use the "top" command and sort by memory
usage (Enter M in the top window). I get

    9:11am  up 4 days, 15:43,  3 users,  load average: 0.06, 0.07, 0.08
92 processes: 90 sleeping, 1 running, 1 zombie, 0 stopped
CPU states:  4.4% user,  2.3% system,  0.0% nice, 93.2% idle
Mem:    94196K av,   82432K used,   11764K free,       0K shrd,    4812K
buff
Swap:  136544K av,   24356K used,  112188K free                   19356K
cached

(Rest snipped)

So spamd is indeed using a lot of memory.
Do you run spamassassin via spamc/spamd or by calling spamassassin
directly? Maybe you get concurrent runs of multiple instances of
spamassassin?
