Hi,

I'd like special sms header parameter that will cause that system will not retry sending sms ( as defined in smsd.conf ) - in case of first error, sending will fail.

For some SMS is better to not be delivered then delivered too late. ( One can retry sending with triggered failed action and decide if retry or drop sms).

Thank you

Since the version 3.1.16 there is a header Retries: 0 available. It was done because of the reasons you mentioned.
