Hi,
I would like to give remote hosts as much information as possible when I don't
accept a certain recipient, under Exim 4.12.
For example, at the moment, I have an ACL which results in this behaviour:
MAIL FROM:<ollie@???>
250 OK
RCPT TO:<ollie@???>
550 Unrouteable address
The relevant part of the ACL is:
deny domains = +local_domains
!verify = recipient
However, when verifying this address from the command line, the reason for the
address being unroutable is more explicit:
root@chaos:[/home/ollie] (74) # exim -C ~ollie/v4.conf -bt ollie@???
ollie@??? is undeliverable:
This customer does not have a @clara.net address. Please try <ollie@???> instead.
That is achieved by the following router:
net_email:
driver = redirect
condition = VOODOO_MAGIC
data = :fail: This customer does not have a @clara.net address. Please try <MORE_VOODOO_MAGIC@???> instead.
domains = clara.net:*.clara.net
retry_use_local_part
allow_defer
allow_fail
I've replaced some complicated lookups with VOODOO etc. for clarity.
Is there a variable which contains what 'data' is set to after this router is
run (i.e. the new 'address'), for use in an ACL, to provide more information to
the remote host about why the recipient was not accepted? I thought
$address_data looked promising, but this was an empty string. :(
Any help would be greatly appreciated. Thanks.
Ollie
