Are you using the latest version 0.3.10 with libsnert 1.63.892?

What OS and version?

What version of Sendmail / libmilter?

You have to enable setuid / daemon core dumps. How to do this varies 
with OS / version. For OpenBSD set:

	sysctl kern.nosuidcoredump=0

Once enabled, core files would be placed in work-dir, which by default 
is /var/tmp. Remember core dumps are only useful if you configured and 
built libsnert with --enable-debug, then configured and built the 
milter. You'll need gdb install to view the core dump.

# gdb milter-null /var/tmp/$filename
(gdb) where
(gdb) quit
