> Throttling is not the solution to fight spam originating within your network. If you know who is doing it, boot him. If you don't, identify who it is, then boot him. Period. Why are you playing paddy cakes with a spammer on your network?
Its not user on my network, rather a stolen password which spammer used to authenticate and spam. Worst part is by the time I came to know there were already 20,000 messages in the Queue, harm was already done. I feel using rate limiting would help prevent that.
