Selected Answer: C
sender_canonical_maps (default: empty) Optional address mapping lookup tables for envelope and header sender addresses. The table format and lookups are documented in canonical(5). Example: you want to rewrite the SENDER address "[email protected]" to "[email protected]", while still being able to send mail to the RECIPIENT address "[email protected]". Note: $sender_canonical_maps is processed before $canonical_maps. Example: sender_canonical_maps = hash:/etc/postfix/sender_canonical Ref: https://www.postfix.org/postconf.5.html#sender_canonical_maps
