qmail-spamt(5) - assign spam throttle parameters to IP blocks

OVERVIEW

       The file /var/qmail/control/spamt  assigns  spam  throttle
       parameters to IP blocks. For example,

          192.168.0.0/24:private:2000:120000::::::

       says  that  mail  originating from IP block 192.168.0.0/24
       will use  /var/qmail/spam/private  as  the  spam  throttle
       directory,  with  a spam throttle delay of 2000 and a spam
       throttle maximum delay of 120000 (both  in  milliseconds).
       All  other  spam  throttle  parameters are unaffected.  To
       define the default spam  throttle  parameters,  define  an
       entry  in /var/qmail/control/spamt with an empty IP block.

       Assignments fed to qmail-newst will be used by qmail-smtpd
       to control spam throttling.  See qmail-newst(8).  A change
       to /var/qmail/control/spamt  will  have  no  effect  until
       qmail-newst is run.

STRUCTURE

       /var/qmail/control/spamt  is  a series of assignments, one
       per line.  It ends with a line containing  a  single  dot.
       Lines must not contain NUL.

ASSIGNMENTS

       A simple assignment is a line of the form

          ipblock:dir:st:stmax:flush:rcpt:tg:tg_resp:

       Here  ipblock is an IP block (format [a.b.c.d][/n]]); dir,
       st, stmax, flush, rcpt,  tg,  and  tg_resp  are  the  spam
       throttle  parameters  for directory (relative path), delay
       (ms), maximum  delay  (ms),  post-DATA  flush,  reasonable
       receipt  count,  teergrube  periodicity (s), and teergrube
       response.  Real-time values for ipblock will be stored  in
       /var/qmail/spam/dir.  See qmail-spamthrottle(5).

       If  there  are  several  assignments for the same ipblock,
       qmail-smtpd will use the first one.

       If an entry exists with an empty  ipblock,  it  is  always
       used to define default (initial) values.

       If several, distinct ipblocks match a given IP address, as
       specified by environment variable  TCPREMOTEIP,  the  most
       specific (smallest network block) entry is used.

       If,  after  applying  all  applicable rules, dir is empty,
       then it will be set to a/b/c/d, where a, b, c, and  d  are
       the  first  four  octets  (in  decimal)  for the remote IP
       address, a.b.c.d.


       The IP address 192.168.2.1 is handled by the fourth  line;
       the  IP  address 192.168.1.2 is handled by the third line;
       the IP address 192.168.0.2 is handled by the second  line;
       the address 192.168.0.1 is handled by the first line.
