I really don't know how to find out:(.
I'm using Bind9 as DNS server, but I suppose the resolver comes from
somewhere else.

I read in the libc6 (gnu libc) FAQ:
  {AJ} The GNU C library uses thread safe functions by default and
libc5 used
  non thread safe versions.  The non thread safe functions have in
glibc the
  suffix `_unlocked', for details check <stdio.h>.  Using  
`putc_unlocked' etc.
  instead of `putc' should give nearly the same speed with bonnie  
(bonnie is a
  benchmark program for measuring disk access).

So I would suppose the thread-safe-ness should be OK (libc6 provides
the libresolv.so.2 library milter-greylist is linked with).

Also, my mailsystem handles about 1 email every 10-60 seconds, and is
idle the rest of the time. So I would have thought that
milter-greylist is unlikely to run into threading problems after only
3 to 5 emails, whitch is what happens every time I try it.

Thanks,
