I just added a new namespace-alias with alias_for.

Apparently this causes all mailbox indexes to be resynced? Is this intentional and/or is there some way to avoid this? My NFS storage pretty much kills itself when hundreds of thousands of users needs to resync indexes :)

Also when removing the alias_for namespace, I have to run a "doveadm force-resync" on the account?

I thought alias_for would be non-destructive to current users?
