Postfix snapshot 20120114 cleans up error handling such that a
daemon process will keep running even when a lookup table can't be
opened.
Instead of terminating immediately with a fatal error, the daemon
process continues execution with reduced functionality, and keeps
providing service that does not depend on the missing table. This
"gradual degradation" approach may be more user-friendly (or
admin-friendly). There is a backwards-compatibility switch if the
old behavior is needed (see RELEASE_NOTES).
Everything else should work as it did before.
This facelift has not yet been applied to postscreen, which still
has the more spartan way of error handling.
