Hi there,

can you please comment on the following approach to "overwrite" locally (i.e. by
machines in my LAN) generated (and possibly faulty) message ids by Exim-
generated (valid) ones?

  if ${mask:$sender_host_address/24} is "192.168.2.0/24" then
    headers remove Message-ID
    headers add "Message-ID: $message_id@$primary_hostname"
  endif

Is this a clever approach? Or am I overseeing something?

Thanks,

Ralf
