Upon running

$ modoboa-admin.py upgrade_postfix_maps <mapfiles>

Modoboa-admin would:

Compare the files modoboa-admin would create in against checksums stored in /modoboa-postfix-maps.chk
If the checksums match, then modoboa-admin gets everything it needs (db type, db name, username, and password) from the existing files, generates new files and copies them over the old files if there is any difference. It would create a new /modoboa-postfix-maps.chk which would contain checksums for the created files.
If the checksum fail or if any file is missing (including the checksum file), modoboa-admin refuses to run.

The checksums would ensure that if an admin has customized the files manually, the upgrade would not overwrite this customization. In such cases, the admin must upgrade manually.

The postfix_maps command would also have to be updated to generate the checksum file when the files are created. This way people who use the stock mapfiles proposed by modoboa would not have to do anything more than run the upgrade command above when upgrading their postfix map files for new versions of modoboa.
