Check the access control on the master agent.
Make sure that the mtaTable is accessible.
Make sure that the 'mibII/mta_sendmail' module
isn't configured into the main agent.
Try walking the NET-SNMP-AGENT-MIB::nsModuleTable.
Check that the mtaTable *is* registered (and this
looks sensible).
If nothing seems to throw light on this, try running
the master agent with debugging turned on.
"snmpd -D" will turn on *everything*, otherwise
you can be a bit more selective.
Compare the output for a single (successful) subagent
request with that for the mtaTable instance. Does
anything come to light?
