KACE Product Support

Sounds like a bug to me. This definitely shouldn't be the expected functionality. What version are you running? Have you contacted support?

If the 'Accept email from unknown users' was unchecked after user accounts were created by email then those accounts would still be able to submit tickets via email since their accounts exist. If those email user accounts are deleted they will no longer be able to create tickets via email now that it is unchecked.

Rich, that won't solve the problem if they are doing LDAP imports.

That's true Andy. We are doing LDAP imports too so all staff have the ability to enter tickets via email and with that setting unchecked it doesn't allow emails from external users to create tickets.

Thank you for your replies; I guess you have well understood the problem. Yes, we are doing LDAP imports and also have configured Kbox authentication via LDAP, The problem become more complicated because we are using more the one queues and each queue have a different set of users but with this problem they are creating Tickets in wrong queue and we have no option to restrict them.
We are not facing problem from External users, all are our internal users using Kbox for different regions with different Queues.
