you may be right. I don't know if any tools like doveadm deduplicate will check for orphans. 
On a new server you could disable sis and use a filesystem with deduplication instead (e.g. vdo)

> This is why I first use doveadm flags/expunge to mark as removed all messages then I use doveadm purge to remove them from storage. I can't use theses commands on deleted/disabled user, I get an error saying the user cannot be found, so I can't remove them from LDAP first.


you could try to stop replication for the user you are deleting:
doveadm replicator remove [-a replicator_socket_path] username
