Different sizes of messages and attachments per users, not global
What I will like to add to Zimbra is to have a global size for attachments like 10 MB, and allow some users to be able to send bigger attachments, or have other users with a lower limit. And if possible to do the above by groups of users.
Is there a way to do this, MailScanner can do this, but I tried implementing MailScanner with a howto online, it didnt work.
In order to change this is it possible to do it with a zimlets or it involves to much work.
