I have updated the postconf(5) text for always_bcc, recipient_bcc_maps and sender_bcc_maps. These three primitives use the same code to add an envelope recipient address. Old: Note: if mail to the BCC address bounces it will be returned to the sender. New: Note: with Postfix 2.3 and later the BCC address is added as if it was specified with NOTIFY=NONE. The sender will not be notified when the BCC address is undeliverable, as long as all down-stream software implements RFC 3461. Note: with Postfix 2.2 and earlier the sender will be notified when the BCC address is undeliverable. I've been fixing documentation bugs as I run into them, time permitting. Wietse
