Dear listmembers, I have a question regarding the correct setup of the lmdb - files. Is it correct (and sufficient ...) to execute a script like this:LMDBFILES="access canonical helo_access relay_ccerts relay \ relocated sasl_passwd sender_canonical transport virtual" for i in ${LMDBFILES}; do ${POSTMAP} lmdb:${PFROOTDIR}/$i done and the (lmdb) files will be used automatically instead of the ascii - versions? Or do I have to execute additional steps to have postfix consider those lmdb - files on startup?
Postfix does not use ascii versions of these files. It always uses a hashed version, - the question is the algorithm/format of the hashed version, - is it btree: or lmdb: or cdb: or something else. And this depends on the software available on your system and the way you use these maps.
Would some kind soul explain the difference between the lmdb - files and the "normal" ascii - data?
A hashed version has a fast-lookup index in one way or another, usually it is some binary form. Ascii files are suitable for editing, while a hashed version is good for looking up individual entries.
