Does the user 'retrain' exist in the virtual_uids table?  Also, you 
really shouldn't need to specify --user to run dspam, the uid is stored 
with the signature data, and I'm running without it...what error do you 
get without --user?  This error also appears to usually be generated by 
a problem with the LDA which is somewhat odd since retraining shouldn't 
attempt to deliver the message.
