I have IMail server version 4.06-98.06.29.
But it seems like my server is now receiving them, trying to deliver them to
the invalid user and then returning them to the "From:" email address,
whereas it seems it should (and used to?) refuse to receive them from the
sending server - which is often different then the domain of the "From:"
email address.
I have mail relaying restricted to only our IP addresses.
