Hi Charles,
There are no operating satellites with this capability to my knowledge. FalconSat-3 was the most recent but has re-entered. MirSat-1 also had some of that capability but was short lived as it was deployed from the ISS.
The Amsat Pacsat program aims to recreate the capability with modern hardware. See here: https://github.com/AMSAT-NA/PacSatDocs And here: https://github.com/AMSAT-NA/PacSatSW
The code runs on a TMS570.
I also have a Raspberry Pi implementation of the Pacsat Server but it has no flight heritage :). See here: https://github.com/ac2cz/pi_pacsat
If you want to know more about this capability then I have a web page that links to the ground station software, it's source code and all of the original Pacsat documents: https://www.g0kla.com/pacsat/index.php

Thank you for the Thybolt information, but again it handles less than one line of a message and just delivers it to it's own ground station. It does not hold a message for another bbs to retrieve it. We are looking for a way to forward full packet personal mail and bulletins via satellite.

Welcome, There were some satellites with such a payload and many are not operational anymore. You can try Thybolt 1 & 2

Thank you, but I was thinking of a fully-formatted packet message that was placed into an orbiting bbs in one part of the world that would be polled by another station, pulled down then deleted from the bird. The message size would definitely be bigger than one line.

APRS Satellites have such a capability, I remember succeeding sending
a
email to myself using UISS thru ISS APRS. For this to work SatGats are needed.

In the past there used to be ground stations acting as a satellite gateway to the store-and-forward birds. I am having some difficulty find which birds are still active that can serve this function. Could somebody point me to the latest information on this? Thanks anyway.
