Re: [exim] Recipient Checking

The docs say that "condition" is used to see if a router is ran...

But I think I'm looking for something that will access the validity of
the response..

For example:

handleuser:
driver = accept
is_valid_address =
${readsocket{/usr/local/mail/sock/recipient}{$local_part@$domain\n}}
transport = local_delivery
cannot_route_message = Unknown user

Anyway to do this ?
