We continue to be dinged for NDR via Lashback due to -0500 X-Failed-Recipients. This occurs even though we have configured exim to not include the subject line, nor anything from the body copy of the original message. So I'm apparently left with only one two choices: 1 - Filter out all outbound and incoming email with "X-Failed-Recipients" in the header. or 2 - Switch on Sender Verification Callouts so that spam email (connections) is rejected rather than bounced. But then I read pages like this:

  Hello, One aspect to keep in mind is that using sender verification callouts is supported, whereas a custom filter rule is unsupported. Also, you may want to consider posting to the Exim users mailing list for help with created advanced custom Exim filtering rules: Exim Users Mailing List Thank you.

  Yes, that's certainly possible. You can search for the term "callouts" on our forums here and you will see a few threads where this is discussed. Thank you.
