Folks,
one of our mailhubs running exim 4.51 has found its way onto the ordb blacklist
for open relaying. The headers of the relayed

Are there any circumstances under which such messages should be allowed through
or can I simply refuse messages with blank from
headers? If the latter is there a routine way of doing this with exim.
Wouldn't you be better off not relaying from anyone
apart from a specific lists of IP addresses under your control,
plus senders who AUTH ?
The route you are taking would only patch that specific test done
by ORDB.
