We got these new Cingular 8525 phones and in trying to enable them to send and receive email on our Exchange 2000 Server he opened the relay now the Queue's are filling faster then he can empty them. The open relay is turned off now, but the Spam is still filling the queues. Many are form a .tw domain, Taiwan and another is Hinet, a China domain. Yahoo fills so fast it will not send for hours. Mail is going out to others but soon the entire server is effected because there are 300K messages waiting to be delivered. How do we stop the influx of Spam?
Right now for Spam we use SpamBayes at the desktop Outlook XP client.
Suggestions would be appreciated,
