I am using system.net.mail for my email application and it works fine, untill I try to send multiple BCC address's. I can't work out why it is failing I get a long message from my try trap which basically says the server response was repeat limit reached. However I don't think it is the server, becasue it comes back too quickly, also if I make the list shorter, ie just 10 address's it still comes back withthe same message, After thining about it I will try just 2 to see what happens.
I think it is some kind of syntax with the emails. like it is finding duplicates or something. Anyone else come accross this.

As an update, I have now tried it with fdifferent amounts of BCC, and it is ok upto 5 then it errors.
