How to Set up SPF Uptime Monitor?

An SPF Uptime Monitor verifies if the SPF record for the given domain exists and if the existing SPF record is correct.

To add an SPF uptime monitor, click the “Create” button in the Uptime Monitor dashboard and fill the fields in the form:

GlockApps: SPF Uptime Monitor settings

Name – enter a monitor name. It is advised to enter the type of the monitor and the domain name, for example, SPF glockglockapps.co.

Tags – enter a tag for the monitor (optional). Tags allows to filter the monitors.

Type – select SPF.

Interval – select the SPF record checking interval. Free monitors work every 2 hours. The interval for paid monitors starts with 1 minute.

Region – select the region: US East (N.Virginia) or Europe (Ireland). GlockApps uses two servers located in two regions and using different IP addresses.

Domain – enter the domain name without http:// or https:// for which you want to monitor the SPF record.

Set the “Active” option to On.

Set “Enable Alerts” to On if you want to receive alerts when an issue with the SPF record is detected.

Alerts can be sent via one or multiple channels set up in Notification Integrations. The default channel is set up via email.

Set “Open a new form after saving” to On if you want to add a new SPF monitor afterwards.

Click “Save Monitor” when you’re done.

What Do the Monitor Statuses Mean?

When the monitor is working, it shows the status of the SPF record on the progressive bar. The green bar means the Up status. The red bar means the Down status.

Click on the monitor name to get a detailed report.

The meanings of the statuses are:

Up – the SPF record exists and is valid

Down – the SPF record doesn’t exist or it exists but SPF authentication will fail because of an error in the SPF record

Degraded – the status changed from Up to Down 

Inactive – monitor is inactive

The Events panel provides a detailed log of the record checks. Here you can get the following information:

Event – shows the record status for the indicated date and time (Up, Down, Degraded)

Date – shows the date and time of the event (record check)

Duration – shows how much time the event status lasts. The tool shows the event status one time per day if it didn’t change. The time when the event status is shown is not fixed. It is calculated approximately. But if a new check detects the status change, it shows the new status immediately.

Response – shows the response returned by the SPF record check.

How to Fix:

You’ll want to read the response if the current status of the SPF record is Down or Degraded to know what you need to do to fix the issue. The most common steps are:

1. Make sure the SPF record exists in DNS.

2. Make sure that no multiple SPF records are added to DNS. Only one SPF record is allowed.

3. Make sure that the SPF record complies with the 10 DNS limit lookup. If it doesn’t, the response will return the appropriate error. You have to remove unused IP or senders from the SPF record or use a flattened record in DNS.
