sms-incoming-queue-limit

this parameter will limit the incoming MO (from smsc) messages right ?

I need to limit the number of messages the bearerbox accepts from the
smsbox, ( and therefor holds in the store file,
the store file can get really big >20MB, the overhead of managing this store
file is then  unacceptable)

when the limit is reached the smsbox will NOT respond with "Sent" from a
sendsms service;

current cvshead smsbox.c has
read_messages_from_bearerbox(void)
{
.......
 } else if (msg_type(msg) == ack) {
     /*
      * do nothing for now. Later we will handle this
      * gracefully...
      */
     msg_destroy(msg);
 } else {
.............
so if the bearerbox can send a ack(with a nack item indicating send-queue
full); the smsbox will set a flag to not accept sendsms messages;

well this is part of the plan, i'd like to get any comments from the group
thanks
