You elided the log entries that show that the message to the archive had two identical recipients in the same delivery attempt. It is difficult to discuss this if you trim the data under discussion. With "always_bcc", and without "receive_override_options=no_address_mappings" the bcc processing happens twice, once on either side of the content_filter. An original message with a single recipient then ends up having three recipients, one the original recipient, and two that are the BCC address. This is what your logs show. My question is whether the delivery failures are also observed when there's only one BCC recipient. Despite whatever perceptions you may have of my tone, which is a consequence of limited time, not disrespect, please take the time to read my posts *carefully*, and follow the suggestions posting the requested results. -- Viktor.
