A "message queue full" error is quite different from a "throttling
error" - at least in my case. 

Throttling error is issued when I'm sending too much messages to
the SMSC. The correct behaviour then is to slow down (I usually
wait for a second per 8 fired messages).

The queue full error is something completelly different (at least
in my case). I get that one when the recepient can't receive any
more SMS-s, and the SMSC has some SMS-s waiting in the queue.
The queue in the SMSC is per subscriber and ussually holds 10
SMS's.

This happens when the subscirber has turned off his phone or is
otherwise unreachable, so the "queue full error" is not going to
be resolved until the subscriber turns off his phone or the
messages in the SMSC are expired.

I think kannel's behaviour to these errors should be accordingly
different.
