AFAIK, SMTP is not used by SMSCs themselves, but is often used by people providing SMS Gateways. (In a previous life, I built an SMTP interface to an existing SMS gateway to make it more accessible for clients that didnt have much(any) technical nouse.)
That may be why you have heard of it - writing a simple script that reacts to a mail arriving to a certain account (sendmail can provide this i believe) and makes a HTTP transaction with Kannel would do the trick. But as Oded says, SMTP has a heavy pay-load and the client would have to be sent a seperate message for success/failure (and if they are sending thousands of emails, it would be complicated to tarry up the status with the original sms as they would have to parse the emails that are returned).
