I have an Exim box which forwards certain addresses to another server, i.e.:
- Exim accepts user@???
- delivers it to server_2 for user_changed@???
Now, server_2 rejects this mail for some reason (user does not exist,
spam etc.). This means Exim will send a non-delivery report to the
original sender. A bit too late, isn't it?
This causes lots of trouble:
- non-delivery reports get to false users (in case of rejected spam/viruses)
- we send unnecessary non-delivery reports for non-existing users; it
should be cut off as soon as someone connects to Exim
I know the proper way to do it would be to have an up-to-date list of
existing users on the Exim box for all "remote users", but it's not
always possible.
