[Exim] virtual alias problem

Hi there,

I have a problem with virtual aliases.

Our office domain, call it office.com, has a wide range aliases and we
have a _Default_ set up that generates a message telling the sender
that they have emailed an unknown address. However the problem with
this is that I want to show the sender the address that is wrong,
incase they mistyped or if it was sent to a batch of addresses.

If I use the LOCAL-PART env var that only reads as
_default_@??? whereas I want to display the original intended
recipient before it was translated to its alias.

Is there an env var for this?

Regards
