Hi Murray,

I'm not able to get opendkim to start w/o forking. I set Background False,
and it still forks.

(gdb) set args -x /opt/zimbra/conf/opendkim.conf -u zimbra
(gdb) run
Starting program: /opt/zimbra/opendkim-2.7.0/sbin/opendkim -x
/opt/zimbra/conf/opendkim.conf -u zimbra
[Thread debugging using libthread_db enabled]
opendkim: /opt/zimbra/conf/opendkim.conf:
dkimf_db_open(): Connect error

Program exited with code 0116.
(gdb) bt
No stack.
