Managing mail with MMDF

Editing MMDF configuration files manually

If you modify your MMDF configuration files manually (using a text editor), keep in mind these guidelines:

Always perform configuration while logged in as mmdf.
Always rebuild the hashed database after modifying files.
If you make any changes to the channel configuration (to, for example, add or remove a channel), restart the deliver(ADM) daemon.

Rebuilding the hashed database

MMDF maintains configuration information in a hashed database for use in quickly verifying addresses and efficiently assigning channels to submitted messages. The MMDF Configuration Manager and the MMDF administration managers rebuild the MMDF hashed database automatically after modifying the configuration files.

However, if you modify /usr/mmdf/mmdftailor or the files in the /usr/mmdf/table directory after running the MMDF Configuration Manager, you must rebuild this database manually each time you make a modification.

To do this, enter these commands as user mmdf:

cd /usr/mmdf/table
./dbmbuild

NOTE: If you specify any options on the dbmbuild(ADM) command line, you must add the -n option as well. This option creates a new database instead of updating the existing one. To watch the progress of the build, enter dbmbuild -vn.
