Just send an email which is received by postfix which sends it to DSPAM.

The info above was from DSPAM built with -g and with the DSPAM-debug
package installed.
In the Zimbra build scripts for DSPAM I noticed that it specifically
uses CFLAGS="-g -O2" so I rebuild the RPM with those flags instead of
the RPM optflags macro [0] and with debug enabled. This has been running
fine for a few hours now. No segfaults. Maybe those optflags are
wreaking havoc.
