--- Comment #27 from Simon Arlott <bugzilla.exim.simon@???> ---
Providing my own user message in the SMTP response is a problem for a defer
because sender_verified_failed is still set and so src/src/smtp_in.c will try
to output it:

  if (f.acl_temp_details && user_msg)
    {
    if (  smtp_return_error_details
       && sender_verified_failed
       && sender_verified_failed->message
       )
      smtp_respond(smtp_code, codelen, FALSE, sender_verified_failed->message);


    smtp_respond(smtp_code, codelen, TRUE, user_msg);
    }
  else
    smtp_respond(smtp_code, codelen, TRUE,
      US"Temporary local problem - please try later");


I don't want to disable smtp_return_error_details because that has other side
effects like omitting some of the content of the verify message.

Instead I've invoked ${acl {...}} on an empty ACL because that clears out
sender_verified_failed. Either an additional configuration flag is required to
stop it outputting the most recent sender verify message, or an explicit
control option is required to clear the last result.
