Oh, you discovered a bug! The last parameter is used to determine
the context in which a trap is generated. Unfortunately, the context
of the generated SNMPv3 trap is not actually set (always ""). By now,
the contextName parameter is only used to check access rights of the
variable bindings in the trap's payload. 

For SNMPv1/v2c the contextName should determine the trap community
through the SNMP-COMMUNITY-MIB. This needs to be fixed too. Currently,
the securityName in the snmpTargetAddrTable is used directly as
community name, which is not correct. Instead, the securityName should
be used in the SNMP-COMMUNITY-MIB to lookup the appropriate community.

Best regards,
Frank
