The GET/GIVE command has been modified to  limit the amount of files any given
user may order a  day. I had always been opposed to this  kind of control, but
it became necessary given  the amount of abuse we have  experienced (such as a
single user requesting over 600 INFO-CPM archive files in a few minutes).
 
This limit  has been implemented  as a new user  exit, LSV$GETQ, to  which all
users  except  the  postmasters  are  subjected.  This  exit  is  passed  some
information about  the file being  requested, as well  as the total  number of
files and total  number of kilobytes of data ordered  'today'. Note that these
numbers correspond to the person that  will actually receive the files, not to
the command issuer.
 
The default  exit supplied with the  code should be powerful  enough to handle
most cases. It will let in any request  originating from or going to a list of
privileged users (GETQWAIVE, defined in  LOCAL SYSVARS), which defaults to the
LISTSERV Coordinators. It  will reject any request destined to  a user who has
ordered more  than MAXGET files  (which defaults to  20) or more  than MAXGETK
kilobytes of data (default is 256k), counting the file being ordered. NADs can
order any amount of data provided they  do not exceed MAXGET files a day (this
is mainly to avoid  loops with 'crazy execs'); in other  words, the setting of
MAXGETK is ignored for  NADs. Otherwise they'd be in trouble  when they try to
order BITEARN NODES  :-) The exit can  be tailored by the  installation to add
more tests for local users, etc.
