I am next working on using local database file lookups for Postfix configuration use.
I see how in the document http://www.postfix.org/DATABASE_README.html to use MySQL and LDAP for some things. With some examples and tests I am sucessful. I see too the example for hash: or btree: or lmdb:. So I can make a definition vi /etc/postfix/test_parameters test_address 1.2.3.4 postmap test_parameters And then query for the definition at the shell make the right result postmap -q "test_address" lmdb:/etc/postfix/test_parameters 1.2.3.4 So I want to now do it the same in the Postfix configuration vi http://main.cf - test_address = 1.2.3.4 + test_address = postmap -q lmdb:/etc/postfix/test_parameters inet_interfaces = ${test_address} I tried also + test_address = `postmap -q lmdb:/etc/postfix/test_parameters` + test_address = lmdb:/etc/postfix/test_parameters But it does not work. I do not see any error with the test. Only that postfix: fatal: config variable inet_interfaces: host not found: `postmap I do not see a good example of this use in the document http://www.postfix.org/lmdb_table.5.html How is it done right? Or better question. Which is a document to do it right? Also I see in the documents many examples for retrieving the parameters for Postfix configuration from a database for use in http://main.cf But is it too possible in http://master.cf ? So for example addrver unix - - n - - smtp - -o smtp_bind_address=1.2.3.4 + -o smtp_bind_address=postmap -q lmdb:/etc/postfix/test_parameters ? *S*
