[imp] Send attachments as links question

[Nicolás Valera]

Hi,

I see that the attachment size limits are applied no matter if the attachments are sent with the message or as linked 
attachments.
Now, when i send attachment as link, the attachment is stored on the vfs defined in the horde conf.php, so, how i can 
set the limits?
- quota in vfs to avoid users fill my vfs
- time for how long is stored

Thanks,
Nico.
