Description: Fortinet FortiMail version 2.20 SNMP MIB providing email security appliance monitoring objects for an older legacy firmware release.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is FORTIMAIL-MIB-220?

FORTIMAIL-MIB-220 is Fortinet's vendor-specific SNMP MIB for the legacy FortiMail 2.20 firmware release, an email security/anti-spam gateway appliance. Its documented content is minimal, centering on basic system identification such as the device's model string, consistent with an older-generation vendor MIB later superseded by newer FortiMail MIB releases with richer object sets. Even so, the intent of such a MIB is system-level status monitoring - identifying the appliance model (and by extension its software/firmware generation) so management stations can confirm which hardware/firmware generation is deployed. No dependency on other MIBs is evident from the available module description, and it appears to be a self-contained legacy Fortinet MIB. It would have been deployed on aging FortiMail email security appliances still running 2.20-era firmware, where FORTIMAIL-MIB-220 SNMP monitoring was limited to confirming basic model identity in installations that have not been upgraded.

IPNetwork Monitor allows you to monitor SNMP objects defined in FORTIMAIL-MIB-220. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Fortinet FortiMail email security appliance (legacy firmware 2.20)

Monitoring Examples

The available data for this module contains no sample object names beyond a general "system model string" description, so a detailed polling scenario cannot be honestly constructed; in practice such an object would be read once to confirm the appliance's model identity for inventory purposes rather than polled repeatedly for operational status.

What Can Be Monitored

How to Use in IPNetwork Monitor

Example using fmlMailOptionsDeferQueue OID:

Select a Fortinet FortiMail email security appliance (legacy firmware 2.20) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type fmlMailOptionsDeferQueue into the Find box to locate it in the OID tree, then select it and click OK. Instantaneous deferred emails number. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
