SMSC can identify it as a spam attempt, since spam analysis is one of the first things to activate before the message is handed over for delivery. I don't think kannel causes any problem in this.
Do remember the buffer limit for each individual number is around 30 or 50 at one time. You might be breaching that as well, after which SMSC is bound to throw error.
