Spam filtering with dspam and postfix

[J. Johnston]

Hello,

I was wondering if anyone knew of a good howto, or some tips for 
filtering spam using dspam in a setup where virtual users (various 
domains) are stored in LDAP. Currently we hand off email to dspam in the 
filter stage and dspam hands it back into postfix as lmtp, the problem 
with this is the current setup uses (and only howto I can find) one user 
for dspam, so the quarantine is under one username, we would like to 
separate this so each user at domain has their own quarantines.

Thanks in advance
