mysql dlr config parms

Hi,

I have noticed that in our config we use these config parms for the dlr-db
group:

group = dlr-db
id = dlr-db
table = dlr
field-smsc = smsc
field-timestamp = ts
field-destination = destination
field-service = service
field-url = url
field-mask = mask
field-status = status
field-source = source
field-boxc-id = boxc

However, in the userguide snapshot as well as the main one, it doesnt
mention the field-source variable... Should this be here, or?

Bill.
