I said:

I see two tables:  One would contain fields for IP, sender
addy, and recipient addy, and the last time it was tried. Call
this the "tempFailed" table.
The other would contain an IP and a time - this would be the
"retriedSuccessfully" table.

That's exactly how I envisioned my "retriedSuccessfully" table
working.  That means I'm still missing a table - what do your other
two do?

That makes sense.
