  Yes ! :-)

  I made raport from 24h:

  Number of mails: 173728.
    < 30s: 88.09%
    < 60s: 3.46%
    <  2m: 1.88%
    <  5m: 3.36%
    < 30m: 2.32%
    < 60m: 0.79%
    >= 1h: 0.09%

  I get only first time from scheduler.perflog without delivery time...
  This is not good :-(

  It's 8:15 now. Why is 288650.1210200 waiting ?

  I have a little modification of router. I changed source directory
  for router (#define in router.c). I replaced directory "router" with
  "clean" and I make antyvirus checking.

  It's 8:24 now. Do you see 288650.1210200 ?

Mar 13 07:59:53 ... router[14651]: S80592AbTCMG7w:
from=<...>, rrelay=STDIN (...), size=2482, nrcpts=3,
msgid=<20030313065934Z288641-29500+29676@...>

  I havent delay and xdelay. Why ?
  My zmailer is: zmailer-2.99.55

  I try to put into router.cf line: trace bind resolv, but it doesnt
  work... Why ?

Pozdrawiam.
