I don't know DSPAM, so this could be irrelevant information, but we did
something like that for training personal SpamAssassin Bayes databases.
Each customer has three SPAM folders (Filtered, LearnSPAM, LearnHAM). If
mail gets dropped into one of the "Learn*" folders, a cron job (which is in
fact a self written, customized IMAP client) finds them, feeds them to a
sa-learn process that uses the customer's Bayes database and finally
deletes and expunges the folder's content. The inbound MTA's SpamAssassin
process uses exactly that database.
The only thing that is potentially problematic about this setup is that
"LearnHAM" mail is removed from the folder and thus has to be *copied* in
the first place to avoid data loss. The big plus of this is that the
personal taste of what is SPAM and what not can be learnt by the email
The described setup is operational here since mid 2006.
