In other words, to attempt the remote SMTP delivery before accepting
the mail?

Not easily, and not in Exim. Think of the current issues:

- Mail loops (ringing). If the remote host is misconfigured to
deliver the mail back to you, and is configured to attempt the delivery
before accepting the message in a manner similar to you, then both
machines would be "nesting" calls to each other without closing any
connections, until one runs out of resources.

- If the message has several recipients, some of which are local, then
rejecting the entire message delivery based on the result of delivering
to one single remote recient would be misleading. That's what DSN's
are for.

Perhaps the days when you could freely forward all your mail to another
host is a thing of the past. Ask the person to read his mail directly
from your server (using e.g. an IMAP client).
