RT Email Error

Hi All,

I have started getting this error with users who email in from one
certain domain. Unless they are setup as users in RT then their emails
bounce saying that I need to grant everyone Create or Reply to rights
to the queue (which i have).

Can anyone please help me with the error.

    CreateTicket (/opt/rt/lib/RT/Principal_Overlay.pm:309)
           You might need to grant 'Everyone' the right

‘ReplyToTicket’ for the
queue test. (/opt/rt/lib/RT/Interface/Email.pm:243)

Thanks
