Well, the most important thing is to get the latest and most accurate status
of the delivery regardless how long does it take. It's my point of view
about the behavior of external Applications.

But that's not true at least for stable 1.2 because ever SIGHUP Kannel
resends the limbo (failed and dlr-notified messages)

Hang on! :-) The message wasn't mal-formed, was it? I've just
intentionally sent a sms with and invalid number whose prefix is not
configured to be accepted by Logica's SMSC, so I got the 0x0000000b. The
same problem seems to happen when I got errors like 0x00000001, 0x00000014
and 0x00000045 ("Message Length is invalid", "Message Queue is full" and
"Throttling error", respectively).
Thanks Oded!
