Just had a look and there may be a way around the quaranteen issue.
Normally when you quaranteen something you have a rule in 'scan
messages#' to skip messages coming from so that messages
released are not scanned and quaranteened again.
However if you were not do do this but instead set a similar rule in
'spam checks =' any messages released from quaranteen would not be spam
checked again but would still be passed through the virus scanner and
re-quaranteed in infected.

I am not sure how to bypass virus scanning for high scoring spam though.
