Thanks for the reference to the 1.8c manual.  I
read it and changed my header in initiate the
probe feature, to wit:

* Auto-Delete= Yes,Semi-Auto,Delay(4),Max(100)
* Renewal=Monthly,Probe

This morning I had a message that probes had been
sent to 1996 subscribers (of around 2300 total).

So, what happens now?  As you can see, I don't use
the autodelete fully automatic setting.  Do I get
reports?  I am curious.

Thanks

Lew
