MIBs are database schemata.  They just describe the table layout in a
hierarchical manner.  An OID is a table, and and OID+instance refers to
a specific row.

Ask the zimbra people if they have implemented mibs.

as for Loadmibs: - you have to be careful to include all of the
prerequisites for it to work.  Look at the IMPORTS section.  LoadMibs
has to read all of the dependencies first - in order - for it to work
right.  And it's a global configuration item, so if you have it more
than one in a configuration file, only the last one will be executed.
