maildrop as the mda for qmail-ldap virtual users?

[Entelin <entelin@xxxxxxxxxxxxxxxxx>]

I am trying to use maildrop as the mda to integrate spam/virii scanning
using virtual accounts,  as in all Maildir's are owned by the same
user/group. Each home dir has its own .mailfilter . Is there a way to
just force maildrop just to use a specific .mailfilter rather than to
let it decide what someone homedir is? 

Thanks
