Refurb vs. Reconditioned emails

[gabester]

What is the difference between "refurbished" and "reconditioned" emails?

Is the reconditioning done on your mail server, whereas refurbished emails are sent back to the originating mail server?

some sort of filtering and buffing/polishing process I suppose.

And do you get the latest available Spam with refurbished emails?

Or do you have to pay for the "Spam upgrade" in order to be current on all the latest Spam "offerings?"

Refurbs tend to come with factory warranties, reconditioned only come with retailer coverage...
