[tangpop2000]

hello,

I am so sorry for ask some problem,

I have Adding DKIM data to my domain after a while, i forgot remove the DKIM data in CLI and i removed the domain in Zimbra Admin UI
Now I cant set up this domain again in my server, shown the error below

unable to modify attributes: ldap host=it.com:389: attribute 'DKIMSelector' not allowed ： ldap.OBJECT_CLASS_VIOLATION Method: [unknown]

When I ruining the command in server try to remove the older DKIM data, i got error

Domain it.com not found.

Thanks ALL,
