Hi all, https://www.postfix.org/postconf.5.html#sender_bcc_maps says
Optional BCC (blind carbon-copy) address lookup tables, indexed by sender address.
but it doesn't specify whether "address" means envelope address, header address or both. OTOH
https://www.postfix.org/ADDRESS_REWRITING_README.html#auto_bcc explains for sender_bcc_maps
Search the specified "type:table" lookup table with the envelope sender address for an automatic BCC address.
Shouldn't that be made as explicit in the manual for postconf(5) too? -- Regards mks
