how can i filter mails from mailing lists to the different virtual users?
Hm, I'm not sure what you actually need. If I get it right, you want to get server-side filtering of mail that is being delivered into mailboxes of users that do not exist on the server?
Cyrus can do that, it has sieve support; and there are web frontends like smartsieve and websieve to deploy the filtering scripts.
