Matthieu,

Thank you, this webpage was most interesting reading.

Emmanuel,

I have reworked 4.0b1 per the "Programming Solutions" part of this
webpage.  Basically I added to "F" option to calls to fopen(), fdopen(),
and popen(), and a I surrounded the changes with "ifdef __sun" blocks.
Attached is my makepatch output of my changes.  I recompiled with gcc
4.2 and reinstalled and I am running this code at my site now.
I will see how it performs and write back.

I have a feature suggestion too.  It would be nice if one could send
a "kill" signal to milter-greylist (like HUP or SIGUSR1) to have the
process dump the greylist.db file.  Then the startup/shutdown script
could be modified so that the db file was dumped right before 
milter-greylist was shut down, eg:

   stop)
         # Stop daemons.
         echo "Dump greylist.db and shut down milter-greylist: ... \c"
 		/usr/bin/pkill -HUP milter greylist
         /usr/bin/pkill milter-greylist
         echo "done."
