Parse From header for delayed failure detection.
Don't check reputation of trusted host.
Track IP reputation only when missing PTR.

+Need to exclude robot users from autowhitelist.  Don't want to have to
+list all users, so implement something like !*-admin@bmsi.com,@bmsi.com.

+Milter won't start when it can't change permissions on *.lock to match
+*.log.  Should maybe ignore that error - the effect will be to set
+the permissions to default.
+
+GOSSiP feedback from user training is ignored because UMIS has already been
 removed from queue.  Maybe keep UMIS in queue, and add method to 
 alter last feedback for ID.

 DONE When bms.py can't find templates, it passes None to dsn.create_msg(),
 which uses local variable as backup, which no longer exist.  Do plain

+<p>  A. The milter source includes a number of deactivated viruses in
