I always configure the GnatBOX GB-1000 with GBadmin.  Last time I used the 
web interface was to install v3.2.0 of the GnatBOX software.  So, it can't 
be the usage of the web interface.

Note, when I noticed it, the GB-1000 I administer just decided to goof 
up.  Prior to goofing up, it was about two days ago before I changed the 
configuration.

What's important here is that it just decides to do it.  No 
user/administrator  intervention is required for the fault to "happen".

I'm not checking the mail server and Gnatbox about three to four times a 
day.  In reality, this is something I don't need to do.  I'm surprised this 
fault has existed since v3.1.3, and maybe on GbatBOX firmware well before then.

Not a good sign.  At least the fault is out in the open and I'm so hoping 
for a maintenance release of the GnatBOX software to be release before 
December arrives.
