Filter messages by contact categories

[laspic]

Presently, it doesn't seem possible to set up a filter rule for messages using contact categories. For example : "redirecting in the folder X all the messages sent by the users listed in the category Y of the address book Z".

However, it would be a very useful feature ! If I want to send messages to contact groups (and that's why this addon is indispensable), I could also want to receive messages from such contact groups, couldn't I ?

Does it make sense to you ? ;-)
