Which version you are using?
I have the same question. Using MEG 7.5.2
partly possible playing with "quarantine configuration ----> Quarantine Queue Settings"
where could be defined the priority of different quarantined queue.
then what is defined as action on the quarantine counts as well i.e. Deny connection is stronger than Accept and ..
plus Virus queue has priority.
What I cannot reach is :
an email has an exe and is Spam ---- > NO notification to recipient. Quarantine content queue. (spam will allow user relelase!)
an email has an exe and in NOT spam --> notify the user . quarantine in the content queue
