It means that the executable file of DeleGate is modified after it is
compiled.  It can be the result of malicious interpolation by others
to the executable file of DeleGate.

You can do the checking manually as this:

  delegated -Fesign

You can test the interpolation as this:

  echo xxx >> delegated
  delegated -Fesign

You can see the history of automatic checking in the LOGFILE like this:

  02/21 12:xx:xx [xxxx] 0+0: -- checked integrity:OK (0.000) 9e22b94e...

When interpolation is detected, it is recorded as this:

  02/21 12:xx:xx [xxxx] 0+0: -- checked integrity:ERROR (0.000) 02d0667...


The integrity is checked using MD5.  Thus if there is a problem in the
generation of MD5, the checking will fail even when the file is not
modified.  There was a bug in MD5 calculation on 64bits machines, but
is fixed in DeleGate/9.2.5.

Cheers,
Yutaka
