well, I did not know that this was the case, so thanks for bringing
this to my attention...
a quick look at the manual (looked for :fail:) and I found this:
If "message" is used on a statement that verifies an address, the
message |
specified overrides any message that is generated by the
verification |
process. However, the original message is available in the
variable |
$acl_verify_message, so you can incorporate it into your message
if you |
wish. In particular, if you want the text from ":fail:" items in
redirect |
routers to be passed back as part of the SMTP response, you should
either |
not use a "message" modifier, or make use of $acl_verify_message.
|
so:
accept domains = +local_domains
endpass
message = Cannot deliver because: $acl_verify_message
verify = recipient
Unfortunately the $acl_verify_message for a standard "Unknown user"
is "Unrouteable address" (I think this is because exim runs out of
routers while attempting to route the address).
Perhaps adding a last redirect router like:
no_such_user:
driver = redirect
allow_fail
allow_defer
data = :fail: Unknown user
would generate the wanted message for unknown users.
