From docs :

"Since iRedMail-0.7.0, quarantining related settings in Amavisd are configured by iRedMail but disabled by default, you can easily enable quarantining with this tutorial.
With below steps, Virus/Spam/Banned emails will be quarantined into SQL database. You can then manage quarantined emails with iRedAdmin-Pro."

Then , what about spam and viruses in free version ? Are them simply discarded/rejected/deleted ?
Is there a log of these operations ?
Where can I configure spam level range for accepted mail ?

Thanks
