It could be that there's a new spam sender out there with unusual
header or HELO information that happens to crash the milter.  The
report_safe stuff shouldn't make any difference.  I believe the redhat
RPMs include all the crashing fixes made to CVS since 0.2.0, so if it's
crashing it's a new bug.  A stack trace might help, or if the machine
is fast enough, run the milter for a while under valgrind and see if it
generates any errors.  I only get around 7k messages/day here, and
valgrind doesn't cause enough load to be a problem on a 500Mhz box.
