The problem is that ClamAV could wrongly state that a message or attachment is 
a virus. Stripping the attachment from the message would then wrongly remove 
something that is supposed to be delivered.

You might think that this could never happen but it does.

And ClamAV does not only scan attachments. It is able to scan images, 
JavaScript, and and and... it is virtualy impossible for DSPAM to know what to 
strip out of a message.

I would strongly suggest to tag virus messages as Spam and let the end user 
have to relase it from the quarantine if she/he is really thinking to need that 
message.

And since you are using ClamAV I strongly suggest you to add additional 
signatures to ClamAV. Have a look here -> http://www.sanesecurity.co.uk/

Especially this little script here -> http://www.inetmsg.com/pub/

When selecting additional signautres then I would only take the low risk (and 
maybe here and there a medium risk) database.

For Sanesecurity I would take:
   doppelstern.hdb
   junk.ndb
   jurlbl.ndb
   phish.ndb
   rogue.hdb
   sanesecurity.ftm
   scam.ndb
   spamimg.hdb
   winnow_malware.hdb
   winnow_malware_links.ndb

For SecuriteInfo I would take:
   honeynet.hdb
   securiteinfo.hdb
   vx.hdb

For MalwarePatrol I would take:
   mbl.ndb

For MSRBL I would take:
   MSRBL-SPAM.ndb
   MSRBL-Images.hdb


Using the above additional signatures should +/- tripple the amount of 
signatures available to ClamAV.
