Hi,

I'm using DSPAM in a 100.000 users e-email structure. I run 6 mail 
server with dspam with the hash driver. The database is kept in a NFS 
share and it seems to work fine.

I'm using TOE training mode, since I have amavis-new in this structure 
doing black/whitelist and common blocks. My users can teach ham and spam 
messages to dspam automatically.

My questions:

Is TOE the training mode that less uses disk space?
What are the hash driver config that I should use? my database is +100GB 
right now and growing fast.
What is the best practice for database maintenance?

this are my settings:

HashRecMax              98317
HashAutoExtend          on
HashMaxExtents          0
HashExtentSize          49157
HashPctIncrease         10
HashMaxSeek             10
HashConnectionCache     10


PurgeSignatures 14          # Stale signatures
PurgeNeutral    90          # Tokens with neutralish probabilities
PurgeUnused     90          # Unused tokens
PurgeHapaxes    30          # Tokens with less than 5 hits (hapaxes)
PurgeHits1S     15          # Tokens with only 1 spam hit
PurgeHits1I     15          # Tokens with only 1 innocent hit


I disabled the dspam_clean and dspam_logrotate from the dspam servers, 
and execute them in the fileserver directly.

I tryed to use postgresql driver, but it used a lot of resources.

Can you guys give me some suggestions? The database is getting bigger 
and I don't know if I'm doing the best maintenance routine.

Thanks!
