Is there a way to have callout verification return false instead of deferring so the behavior can be more controlled? For instance, I have a warn ACL that verifies a recipient, but when the callout defers, exim defers. I want to proceed on to other things if that deferral fails and know that it failed, rather than set defer_ok and have it pretend it succeeded. Maybe setting $callout_verify_status or something? Or maybe this is already done and I missed it.
