Postfix does not make queries with empty strings because some
software can't handle it. You can't use /^$/ patterns for any
Postfix lookup table.
As documented, sender_bcc_maps does not map null query keys to <>.
You can't use <> patterns in sender_bcc_maps.
Use check_sender_access instead. As documented, it maps null query
keys to <>.
