When we close a request, the requester will receive an email. Mostly, they are very happy becuase their problem is solved. So they send a reply on the recieved email, and thank us for helping them. :P :P :P
But..... that email is being fetched and their request is reopend again!!!!! This happened us several times a day.
How can we solve this issue???
I thuoght it was a bug, but the SD Helpdeks told me it isn't. I had to make a SPAM rule which reject "Thank you" messages.
