There's no good way to do this with passwd userdb. It would have to be some kind of a new exclude list of users, which is a rather annoying special feature to implement.

I'm using PAM with padl_pam as a backend to get the users from an ldap server.

userdb { driver = passwd args = blocking=yes uid=XXX gid=XXX }

passdb { driver = pam args = failure_show_msg=yes dovecot }

Thanks, Daniel

i'm searching for a way to exclude certain users from dovecots replication mechanism.

I can't use the first_valid_uid setting, because the uid of my pam (ldap) users und my system users are mixed up.

So, is there a way to limit my users i currently have in my userdb or somehow exclude specific uids from replication?

Which userdb do you use? For example with SQL you could change the iterate_query not to return all users for replicator.
