If you want to produce case-sensitive and case-preserving map with postmap(1), use -f option that tells postmap to NOT fold keys into lowercase as it does by default. cdb(1) utility from the tinycdb package does no modifications to the data items you feeds it, hence it's always case-sensitive. But note that postfix internally almost always lowercases addresses before looking it up in various maps, to achieve case insensitivity of addresses, -- hence, if your map contains keys in UPPER case (as cdb(1) or postmap -f produces), postfix will most likely not find them. This is by design. /mjt
