Problemes with Quarantine infections

[liste.gug at free.fr]

Hi,

I'm using Mailscanner patched for clamav support, on a smtp gateway.

When I send infected attachement, I'd like that attachement was save to the
Quarantine Dir.

It's work great for spam but not for virus ... I don't know why ...

My options are :

Quarantine Infections = yes
Quarantine Silent Viruses = no
Quarantine Whole Message = no
Quarantine Whole Messages As Queue Files = no
Quarantine Dir = /var/spool/MailScanner/quarantine
Quarantine Permissions = 0644
Keep Spam And MCP Archive Clean = no

Have you any idea ? thank you in advance.
