Actually, only by 1. Contrary to the docs, retryable failures (4xx status, SMTP errors) are simply queued and retried. Only permanent failures (5xx status) are scored and these are all scored as 1, even so called soft failures such as a full mailbox. > * is reset > only if no bounces occur within bounce_info_stale_after days Correct. > In particular, the score is *not* altered when a message is delivered > successfully.

Because no one ever implemented it. It would be kludgy at best to do because no event occurs for a successful delivery so we would have to remember every message that was sent to a user and every bounce received would have to be matched to a sent message, and then when a bounce was received, we'd have to check that there were no messages sent before that that didn't bounce, and even that isn't good enough because sometimes bounces can be delayed for several days or more and there's no guarantee that they are reported in the order that messages were sent. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California Better use your sense - B.
