Cellular operators know that their clients expect speedy delivery of SMS, including those sent via SMTP. They know better than to introduce greylisting latency at the gateway when there's already normal latency at the SMSC. Have you confirmed with your cellular operator that they don't offer additional gateways; e.g. based on ICQ, HTTP and whatnot? Most likely, they don't offer SMPP-over-TCP connections to end-users ( http://www.smsforum.net/ ), but probably to a couple of third-party providers that you could use instead? -cpghost. -- Cordula's Web. http://www.cordula.ws/
