I think it would be great if there was a way to see which station was used as a relay with VMAIL that has been received, and perhaps even a way to automatically send a reply back the same way.
I.E. I received a VMAIL from station xxxx that was sent via a relay. I have no way of determining what relay station was used, when looking at the VMAIL later, as it only show the author of the VMAIL.
Perhaps something like wd4aaa@wd4bbb in the callsign field for the author of the VMAIL if it was sent via wd4bbb.
This information could also be saved, so that a reply, or new message would be routed the same way.
...Just a thought, as I don't know what restrictions are imposed by VARA. Perhaps some programming "black magic" could be used to indicate the relay when VMAIL send or received, which would make VarAC initiate a contact to the relay station, and then send mail to the originator?
