My understanding is that always_bcc does not work: - if receive_override_options includes no_address_mappings; or - after Postfix has forwarded mail internally; or - for mails generated by Postfix itself

We'd like to debug some emails sent through a multi instance withouth having any impact on the mail flow so I have added always_bcc=de...@whatever.com to the main.cf of that instance and reloaded it. But instead of sending copies of the emails to the debug address, postfix relays both the original and the bcc emails to the relayhost of the multi instance as well. This is postfix v3.2.10 on a SLES 12 SP5 server. Is this the expected behaviour?
